Sup! Same prob here! :)
Fallout 3 kept freezing randomly mid game, sometimes 3 times within an hour, sometis I could play 3hours without it freezing. So i found this mod from this site and installed it. But when I choose this file "unofficial fallout 3 patch.esm and Fallout3.esm from the "data files" and press PLAY, it crashes almost immediatly.
I have no other patches and I bought it from Steam + no DLC. So where did I go wrong?
Thnx!
