Stalker Shadow of Chernobyl loosing Color Correction

When starting the Game, the Color Correction is actually applied correctly.
However, as soon as you start the game or load a savegame the colors will be reset once you enter the game (loading screen is still colored correctly).

Stalker is a x32 Application which supports both DX8 for static Lightning and DX9 for dynamic Lightning. I'm using Dynamic Lightning so I use the cclutch_ix.dll

The Stalker SoC Version I'm using is 1.0004

I'm using this on an nVidia 470 with Forceware 285.62 on Windows 7 x64

This is all debug Information, from Start of the game, loading a savegame and then quitting. If anymore information are needed I'll try to provide them..
