EXCEPTION_ACCESS_VIOLATION 0023:01221D16

No should not be. Hmm, to be sure if you browse the local files of Amnesia (right-click on game in steam, properties, last tab), temporary move the msvcr71.dll and msvcp71.dll out of the folder in case they cause a conflict and then try to run the game again.

If not working..

Try turning off steam overlay for the game (in properties in steam) and also try starting the game or launcher directly from the folder by running launcher.exe and amnesia.exe.
