Can't play in Fullscreen

[Gnemesis]

For some odd reason I can only play in windowed mode. Starting the game in Fullscreen causes an immediate crash, resulting in this message:

"Amnesia.exe caused an EXCEPTION_ACCESS_VIOLATION in module atioglxx.dll at 0023:690936B1, DrvPresentBuffers()+118609 byte(s)"

Just thought i'd mention that i just updated my graphics drivers after fully clearing the previous version. I've also poked around with the game options with no success.

Does anyone have a clue as to why this is happening?

Here is the hlp log if it helps
