White Cars Problems

I recently uninstalled my GP4 game, due to some problems with the zak tool. I then try to reinstall the game, which went ok, until I try to add the offical 9.6 patch. I keep getting a message that says "GP4 is already updated" even though it's the first time I have run the patch. When I start to run the game , various parts of the cars are white. My ingame setting, (manual advance settings) are set to the hightest setting.
I have uninstalled the game, and check the registry for any infogrames entries, but I can't seem to find anything related to gp4. I also notice, when the game is installed, I can't identify any gp4 entries in the registry. I am currently running windows 7 64 bits. Can someone explain how to find the patch on my computer.
