I doesn't see any skin only clothes and hear

Today I replace my old VGA card with Radeon 2600 XT. When I log into SL on my avtar I can see only clothes and hear. The same thing is with others persons (which see me normally). I can't see any skin, as all people become invisible. New VGA is running normally (I play some others games). I install drivers twice but this didin't help. I also install fresh version of SL, but problem still exist.
I need your help how to solve this problem.

You can't see the avatar bodies, but you can see their clothes? By clothes do you mean all of their clothes, like pants and skirts, or only attachments, like flexi skirts and hair?

I have the same problem.. Im transparent unless I fly or go into appearance mode. I havent changed anything since the last update so I know its not my problem. WTH is it!!!????
