I installed brand new Win7 64bit; new V10 and V11 and I got errors - Vegas is crushing!!!!!!!!!
video card GTX470, Asus super solid mobo with new drivers...and it keeps crashing. I am fed up with this issue....will consider moving back to Premiere. see attached pics with description of error (can't copy paste it from Vegas error windiw!)

If you haven't seen, many of us find that it is best to unistall Vegas 10, it's a big help for some people.

Turn off GPU acceleration, uninstall Vegas 10 and see what happens. Hope that helps.

It doesn't matter in my case...it started on 10a, ...10d, 10e so I downloaded 11 and it is the same; is it DirectX11??? what the h... is going on?
everything is bran new installed and system was re-installed yesterday!!!

You should uninstall 10 anyway, what do you have to lose? If Vegas 10 does not mix with Vegas 11 for a lot of people, you should try removing it. Unless you have another idea.

Does it only happen when opening that specific VEG file? It looked like you were trying to open a project at the time. There may be an issue with that specific project instead of an actual issue with Vegas. Can you start a new project, add files, and do some editing without crashing?

no matter what project...now I unistalled V10e so it onlt V11 but it crashes even more often. here is the one of the error code:

Well... that was hard to read...

I see two files listed and don't know which caused the error: Vegas110.exe and mscorwks.dll. Now the question is Which one caused the actual crash?
