i have a problem

hello everybody.
i have a problem with the game.
well you all think: why u post it here and not on the nexon forums?
look:
when i play i have always white walls, and it don't goes away...
i have changed game modes but nothing helps.
now i'm redownloading CA and i hope it's gone.
i have used some hacks, but they are patched now and i don't know how to get the white walls away.

if somebody can help me,
thanks!!!

one of your hacks would have been a texture editor and it will have deleted or replace certain file's. re-install will fix this.
