Backed them up and restored: Nothing.
Uninstalled and reinstalled: Nothing.
Repeat: Do not install this. It may fuck up your game.
when you install this, you only change 2 files, if you reinstall those two files, it goes back to the same state it was in before you installed it.
If you've done that and there's still a problem it is not down to this patch, it is another problem with your computer/game. Fucking obvious imo.
