&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p&gt;Design Database projects may stop functioning or generate a Timeout error on opening.&lt;/p&gt;
&lt;h1&gt;Introduction&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Vital&amp;nbsp;project information and data in relation to your CAD model is saved in&amp;nbsp;your project folder&amp;nbsp;in the form of&amp;nbsp;Microsoft Access Database files.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Should any of these files contain invalid data, or be incomplete,&amp;nbsp;then&amp;nbsp;Design Database&amp;nbsp;may struggle to open the project. This can result in the aforementioned &lt;em&gt;&amp;quot;Timeout accessing the database&amp;quot;&lt;/em&gt; error, or the Design Database menu refusing to appear. However if you inspect Task Manager you should find that it is actually running in the background:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Solutions&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;If possible a back up copy of the project should be sourced. If no backup exists, or a lot of data has been added to the project since the last backup then you should contact Bentley Hevacomp support who may be able to recover the project data.&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#1e90ff;"&gt;Please note that while Bentley Hevacomp support will do their utmost&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#1e90ff;"&gt;to recover a damaged project, success cannot be&amp;nbsp;guaranteed.&lt;/span&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Prevention&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;These issues&amp;nbsp;are&amp;nbsp;caused&amp;nbsp;when&amp;nbsp;Design Database is prevented from updating the project&amp;nbsp;folder. The following are some reasons for this, and should be avoided if possible:&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;Forced shutdown while project is open&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Machine crash&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Manually editing data files within the project folder&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Insufficient Windows permissions to the project folder&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Server reboot while project is open&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Communication issues between server machine and client&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Solutions&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;If possible a back up copy of the project should be sourced. If no backup exists, or a lot of data has been added to the project since the last backup then you should contact Bentley Hevacomp support who may be able to recover the project data.&lt;/p&gt;
&lt;hr style="width:100%;" /&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;"&gt;Please note that while Bentley Hevacomp support will do their utmost&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;"&gt;to recover a damaged project, success cannot be&amp;nbsp;guaranteed.&lt;/span&gt;&lt;/p&gt;
&lt;hr style="width:100%;" /&gt;
&lt;p style="text-align:justify;"&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Prevention&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;These issues&amp;nbsp;are&amp;nbsp;caused&amp;nbsp;when&amp;nbsp;Design Database is prevented from updating the project&amp;nbsp;folder. The following are some reasons for this, and should be avoided if possible:&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;Forced shutdown while project is open&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Machine crash&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Manually editing data files within the project folder&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Insufficient Windows permissions to the project folder&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Server reboot while project is open&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Communication issues between server machine and client&lt;/li&gt;

&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p&gt;Design Database projects may stop functioning or generate a Timeout error on opening.&lt;/p&gt;
&lt;h1&gt;Introduction&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Vital&amp;nbsp;project information and data in relation to your CAD model is saved in&amp;nbsp;your project folder&amp;nbsp;in the form of&amp;nbsp;Microsoft Access Database files.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Should any of these files contain invalid data, or be incomplete,&amp;nbsp;then Hevacomp may struggle to open the project. This can result in the aforementioned &lt;em&gt;&amp;quot;Timeout accessing the database&amp;quot;&lt;/em&gt; error, or the Design Database menu refusing to appear. However if you inspect Task Manager you should find that it is actually running in the background:&lt;/p&gt;

&lt;h1 style="text-align:justify;"&gt;Solutions&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Should you come across these issues then you will&amp;nbsp;need to:&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;Revert to a back-up of the project in working state&lt;/li&gt;
&lt;/ul&gt;
&lt;p style="text-align:justify;margin-left:30px;"&gt;or:&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;Contact Hevacomp support&amp;nbsp;to see if the project data can be repaired&lt;/li&gt;
&lt;/ul&gt;

&lt;h1&gt;Introduction&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;From time to time you may find that the Design Database menu does not appear after opening a particular project. Likewise, a &lt;em&gt;&amp;quot;Timeout accessing the database&amp;quot;&lt;/em&gt; error may occur, resulting in the software shutting down.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p&gt;&lt;span style="font-size:small;"&gt;This document provides information on why a Design Database project may be inaccessible, and solutions to prevent this occurring.&lt;/span&gt;&lt;/p&gt;
&lt;h1&gt;Introduction&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;From time to time you may find that the Design Database menu does not appear after opening a particular project. Likewise, a &lt;em&gt;&amp;quot;Timeout accessing the database&amp;quot;&lt;/em&gt; error may occur, resulting in the software shutting down.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Explanation&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Vital&amp;nbsp;project information and &lt;span style="font-size:small;"&gt;data in relation&lt;/span&gt; to your CAD model is saved in&amp;nbsp;your project folder&amp;nbsp;in the form of&amp;nbsp;Microsoft Access Database files. &lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Should any of these files contain invalid data, or be incomplete,&amp;nbsp;then Hevacomp may struggle to open the project. This can result in the &lt;span style="font-size:small;"&gt;aforementioned &lt;/span&gt;&lt;em&gt;&lt;span style="font-size:small;"&gt;&amp;quot;Timeout accessing the database&amp;quot;&lt;/span&gt;&lt;/em&gt;&lt;span style="font-size:small;"&gt; error, or the &lt;/span&gt;Design Database menu refusing to appear. However if you inspect Task Manager you should find that it is actually running in the background:&lt;/span&gt;&lt;span style="font-size:small;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-18/6354.1.png" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;&lt;/h1&gt;
&lt;h1 style="text-align:justify;"&gt;Solutions&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Should you come across these issues then you will&amp;nbsp;need to:&lt;/span&gt;&lt;span style="font-size:small;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Revert to a back-up of the project in working state&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p style="text-align:justify;margin-left:30px;"&gt;or:&lt;span style="font-size:small;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Contact Hevacomp support&amp;nbsp;to see if the project data can be repaired&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;h1 style="text-align:justify;"&gt;Prevention&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;These issues&amp;nbsp;are usually caused&amp;nbsp;when Hevacomp is prevented&amp;nbsp;from writing data to the project folder. The following are some reasons for this, and should be avoided if possible:&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Forced shutdown while project is open&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Machine crash&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Manually editing data files within the project folder&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;Insufficient Windows permissions to the project folder&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:small;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Server reboot while project is open&lt;br /&gt;&lt;br /&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Communication issues between server machine and client&lt;br /&gt;&lt;br /&gt;&lt;/span&gt;&lt;/li&gt;
