What changed?  That is what you will have to find the answer to.  If it worked and now it doesn't, you need to find out why.

1.  Windows updates? 

2.  Video Drive update?

3.  Virus or spyware?

4.  Updated the Autodesk software with a SP or hotfix?

5.  Installed additional software that may have modified .NET or C++?

Something changed...

If you can pinpoint a location when you remember it working, you can try a system restore back to that date and see if the problem is fixed.

Good Luck!

Is it an activation crash?
