hey everybody, so, i just bought ArmA2 through gamefly. i downloaded and installed no problem. activated no problem. when i try to run the game, it goes to start and then quickly crashes and gives the error "bad animation file format in file". Now, when i look up this particular error, i found that to fix this, you have to go to the steam website and and then right click on the game, properties, local files, and then validate game cache... or something along those lines. i downloaded and registered with steam, but i didn't purchase the game through them, so how do i do this fix for my copy of the game? someone please help me because i long to play this game and i just got a computer that's decent enough to run it. thanks in advance.
