Weird error based on timing?

[Carson]

real quick, i have an hp 8560w, the one with i5 2.6ghz and quadro 1000m 2gb. I run amnesia, first start level fine, intro fine, but once i go down the stairs in to the next room, i get the error after being in the room for a few seconds:

Amnesia.exe caused an EXCEPTION access viol. blah in module nvogl32.DLL at 0023:5FDF1DAA, DrvPresentBuffers()+1819082 bytes

xxxx32.DLL... might be stupid but i have a 64 bit system, is this dll for 32 only or something?

Thanks.
