I'm glad you bumped this. I'm having a hard time keeping track. Not that I'm an official anything, I just don't like to leave people hanging.
This is bugging me because poking around it sounds like and antivirus is blocking it, but that doesn't explain the multiple instance error. I guess it can't hurt to double check though. The recent patches are causing new flags that, even if you already made exemptions, are going off. You'll have to redo those exemptions, I think, is the gist.
@WanderingAries You're clever. Any ideas?
