    Problem Description

    When opening the software you get an error message that says "System.NullReferenceException: "Object reference not set to an instance of an object." and the software closes.

    Reason

    The library.config file becomes corrupt

    Steps to Resolve

    Delete the library.config files

    1. Make sure the software is closed and browse to "C:\Documents and Settings\(user name)\Application Data\Bentley\EngineeringLibraries\" (for Windows XP) or "C:\Users\(user name)\AppData\Roaming\Bentley\EngineeringLibraries

    2. Locate the "libraries.config" and "libraries.config.bak" file and delete them

    3. Reopen the software
