To get a few things out of the way: I am on Windows 7 but my Steam folder is not in Program Files (and that annoying as hell UAC is off), BOSS is in the correct folder as far as I can tell (oblivion/Data right?), BOSS for Fallout 3 works just fine I used it yesterday.
This is a brand new installation of Oblivion, I wanted to start fresh before installing FCOM, I haven't even started with FCOM yet my load order is currently just all official plugins and Unofficial patches. BOSS worked on my previous installation, and as far as I can tell I haven't done anything different. Any help?
