I've only seen this error when there had been some dll preloaded that tried to mess with the game.
Wallhack anyone?
Wow.. you're pretty quick to judge. If I was going to cheat, I'd pick a cheat that worked. -_-
But I don't cheat, and I hate people that do. I'm just asking for advice, cause I'd like to play trem again.
I recently reformated my computer, that's why I lost trem. I've installed all my drivers, though. I agree, it's strange. That's why I came here.
More constructive advice anyone? :/
