Exception_Access_Violation at startup

[RawkBandMan]

Hey guys I pretty much have this problem, except it happens in-game, and my video card is a ATI Radeon X600. (Below the requirements, I know. Damn Steam giving incorrect requirements) I've had very few problems with this, but since the 1.02 update or whatever, I'm crashing frequently. I crashed last nite while opening it, my screen went all wacky on start-up of Amnesia, and I was forced to shut down my PC. I tried again this morning, did the same thing, forced to shut down my PC. I tried again after restarting, it worked, but I went into the game, played 5 minutes, paused it, went to the options, and as soon as I clicked it it crashed saying
"Amnesia Crashed" or something, and the tab was Anylizing the crash, then that stopped responding, and then it just told me Amnesia.exe was not responding, and forced it to shut down. Help?
