Trainer works fine with Steam download from September 25th 2012 CoD black ops, the games exe detail tab doesn't tell you what version or patch version information, but I just went with the flow and the trainer worked!..
Jumping in late to this thread. I have 8.1 OS. When I tried to use a trainer for MW3 it shut my system down. Is this also still the case for Black Ops 1? I'm getting fed up with a tiresome segment of the game and want to use a cheat but dislike watching my rig crash, plus I'm wary of Steam banning my account even though I never play multi.
Anybody having any luck lately with this game trainer with 8.1? I downloaded the game about 3 months ago.
