I'm getting this "Exception access violation" error. Amnesia is constantly crashing in exactly the same place (in Cistern). The error reads: "Exception Access Violation in module nvogly32.dll" (there is a lot more to the message but this was all that I managed to write down before the message stopped appearing; now when it crashes the screen just goes black and freezes there). 
I've been through your trouble-shooting guide and have tried just about everything. When this was happening in an earlier section/map, turning off VSYNC did the trick, but apparently something is needed now, and I have no idea what. In case it's helpful below is my hpl detail, but mine doesn't say "GDI Generic". Please help.
