Multiple colors! :O

[Horror]

Hi
Ive just recently installed Penumbra: Overture and it went smoothly. After running the latest patch, I eagerly watched the opening storyline - very interesting!

My problem is though, on the first level literally everything is multicolored (alot of purple, pink, etc).

Screenshots:







What should I do? Ive installed all my drivers (display/sound) , patched Penumbra, reinstalling, and even playing around with the graphical settings. I can run it on max settings (cause it was max'd my default) so im stumped here guys. =|
