Thanks for this great software and your time. Happy to enable donations on it.

However, I do have one machine that I can't launch multiminer on - it worked for a few days then stopped working.

Detailed error below:

Any thoughts? As you can see from the OS version, it's windows 7, 64-bit. I feel like this might be a .net framework issue but I uninstalled all frameworks that I could find in programs and features, and reinstalled 4.0. Any other thoughts?
