Hi, i just bought the Penumbra pack off steam. so i started Overture and you start off in That cabin on a ship i do everything in there ok then i leave i get the first sentence on the next screen then when i click to continue the game crashes with this error...

penumbra.exe caused an EXCEPTION_ACCESS_VIOLATION in module ntdll.dll at 0023:778d 3592, RtlEnterCriticalSection()+0018 byte(s)
