I am in the same boat... the app used to work on my Win8 pc beautifully, now I get a blue screen, and it maxes out one of my processors. It is like there is some loop it gets stuck in.
I have uninstall/reinstalled, etc...
I am willing to help in any way to get this resolved. I am a developer myself, if you need someone to run a debug version, etc. please let me know.
