Everytime I click on the toolspace icon on the ribbon, a message saying "FATAL ERROR: Unhandled Access Violation Reading 0x0000 Exception at dbdb872bh" comes up. A new window then shows up asking about sending an error report. Does anyone know what is going on here?
I included an attachment so that you can have an idea of what is going on
That's very odd. Sounds like an installation issue. Try a repair, if that doesn't work, remove it and reinstall it.
One other thing you can try, if you're comfortable with editing the registry:
The HKEY in that article is for 2010, you'll have to edit the key for 2011.
Not quite what I expected on the version - I get Product Version: E.116.N.0, AutoCAD Civil3D Version 2 - indicating that I've applied Service Pack 1
I suppose it might have been easier if I asked "have you applied the latest service pack...."
If it doesn't say "Version 2" then you probably don't have the service pack applied. I'd try that first.
