3.0 Crash VS on Graphics Debugging

After updating Parallel NSight to and my drivers to 320.0, Visual Studio 2010 crashes less than a second after starting my app through graphics debugging.

The exception thrown in VS is System.Reflection.TargetInvocationException, with inner exception “Cannot access a disposed object. Object name: ‘MarshalingWindowFrame’”.

Running Windows 8 x64.

Any ideas?

Actually, just fixed the problem. I uninstalled Nsight and PerfHUD, ran devenv /resetsettings from the VS command line, and reinstalled NSight. Seems to be working fine now :)
