My desktop install just...vanished. It was there yesterday and today it's not. It still appears in add/remove programs, but I can't uninstall it because it can't find the file to uninstall. The folders are there, but the .exe is gone.
EDIT: I figured out the problem. My antivirus flagged an update as IDP.GENERIC and quarantined everything.
What little I was able to play was intriguing. Half the time, it doesn't start, it's just opens a blank white screen.
