Man....I have a big problem.

I change my loction for store game files from D to C programdata..maniaplanet.
What you can do with the launcher and click on help.
The other folder is in orginal place in Documents maniaplanet.
So all maps are on the normal places so to say.
But now i have very weird texture ingame!

When i start the game first it looks ok.
But when i start a game..it's all black and white.
Texture and colors are gone

I did already clean cache.
Remove a lot files..so updated it again.
Tryed the maniaplanet installer which i download.
So far..no succes...grrrr

Maybe any of you know how to fix this?
Thanks for your help
