I was wondering if there was a legitimate way to revert back to version 1.1. I'm quite paranoid when it comes to all things Steam, so I'm a bit apprehensive about using certain files that were uploaded to revert back to version 1.1. Unfortunately, I don't have Windows 7 so I can't utilize the "shadow copy" feature and I didn't have the foresight to make a backup (I honestly didn't think a patch could fubar the game to such an extent).

So I'm just wondering if there's a more legitimate way to revert back to 1.1 because I'm not sure if I can wait a week for things to get sorted (According to Bethblog). All help is appreciated.
