Receiving lots of Run Time errors and crashing

The run time errors are as follows:

01-Sept 15 8:40 am: Run Time Error ‘0’

• I was editing the columns in the Borehole tab of the Main Group tab of the Input page. I checked the “Do not display” box for the Notes column. I was then prompted to save changes to continue working.

01-Sept 15 8:41 am: Run Time Error ‘3422’ – Cannot modify table structure. Another user has table open.

• Dialog box showed up when I clicked OK in the previous run time error box.
• There is no way another user had the table open, let alone gINT. gINT is currently only installed on two machines, mine and the computer with the big screen across the room from my desk so we can ensure we don’t have the program open on more than one computer.

01-Sept 15 8:43 am: Run Time Error ‘-2147418105 (80010007)’ – Automation error

• Dialog box showed up after I clicked OK in the previous run time error box.
• gINT shut down itself.
• When I reopened gINT the changes I was trying to make had been saved.

01-Sept 15 9:31 am: Run Time Error ‘0’

• I was editing the User Report Variables table and hit the cancel button.

01-Sept 15 9:31 am: Run Time Error ‘-2147418105 (80010007)’ Automation error: The callee (server[not server application]) is not available and disappeared, all connections are invalid. The call may have executed.

• Dialog box showed up after I clicked OK in the previous run time error box.
• The boxes closed and gINT did not shut down.
• gINT stopped responding and I had to close the program manually.

Any ideas?
