I have never run into this specific problem, but a quick glance online leads me to believe that your .NET installs may have been corrupted somehow. Microsoft puts out a tool that attempts to repair .NET.
i have tried everything in this thread but still has problems. Installed 3.3.1 Beta and that one works, but everytime i'll try to update, Virb Edit shuts down while starting up? Any ideas and hope a new version is coming soon.
I'm sorry to hear about the problems you're having. Unfortunately, we aren't able to reproduce this issue. All the research I've done still leads me to believe that your Windows and/or .NET installs have been corrupted somehow. Do you get this issue for any other programs on your system, or is it just VIRB Edit? Here is another link with issues similar to these, with some solutions that seem to have varying degrees of success.
