Penumbra Crash At Start - ATI Radeon 9600 the cause of the issue?

[tangledweb]

Hi everyone.

I recently purchased The Penumbra Collection, and have been having problems getting the game to start. Every time I start the game, I receive an error:

"Penumbra.exe caused an EXCEPTION_ACCESS_VIOLATION in module
atioglxx.dll at 001B:6954AC8E"

I've updated my graphics card drivers (I have a Sapphire Radeon 9600), and even replaced the Penumbra.exe file has mentioned in this thread: http://www.frictionalgames.com/forum/thread-3328.html

Any help would be greatly appreciated!

I've included screenshots of the error messages here:
