Exception Access Violation

[phattline]

I just downloaded Amnesia off of steam, and it consistently crashes every few minutes. I went through the troubleshooting thread and couldn't find this specific error. I did try setting my graphics settings far lower than they should have to be set (I have a GeForce 9600). I wanted to try running it as administrator (I'm using Vista 64-bit), but since I'm running it through steam I don't know if that is possible. If it is I haven't figured out how. Unfortunately, there are not any drivers for my graphics card that are more up to date than several years ago because Microsoft doesn't care about 64-bit. Anyway, I got an error report from something called Blackbox. This is what it said.

Exception_Access_Violation in module nvoglv32.dll at 0023:6976DCB5, DrvPresentBuffers[]+87845 byte

I've attached the error log from Blackbox. Also I read a similar thread and they requested the hpl log from amnesia also so I've attached that.

This game is awesome and I really want for it to stop crashing because it really kills the vibe for me. Any help would be appreciated.
