Actual Gamma stuck at setting '1' - JENS TAKE A LOOK PLEASE

[plees]

If you can not prove that you own a legal copy of the game then we have no obligation to help you out.

What was this shop called?
Do you have a serial key? If so do NOT post it here, send it off to Jens. It might help.

I'd like a response from the Jens guy, instead of from some guy, whose first act to help me, was to tell me that his game worked fine with a completely different gfxcard.
