Any idea?

I'm getting the same error on my PC. Any suggestions for how to fix it? I was out of town for a week and came back to this, so I don't know what changed. I do believe there was a Windows update on Jan 11 which may have caused it. I'm running Windows 7. I have the error log that was generated if that helps.

Hey @SherryJ, thanks for your nudge.

Since you're on a Windows computer, please do send along the error log from the error message you received, so we can investigate.

Thanks!
