Problem regarding avi's shirts and undershirts and other kind of clothes in appea...

Hello, just wanted to know something about if someone had same problems as I had, because this is some seriously bullshit (sorry for the language). Okay we'll go to the case, in about a month I had a problem, and I still have, and it's when trying to wear shirts and stuff, my body is going all white, black or the color of the shirt/pants. I've tried to follow some guides from people that had same problems. But nothing even helped...

So do any of u out there have a solution for this? Because I even dont think it will help with a upgrade on my graphics driver because it isn't the graphic card that decides how my clothes should look like by others.. So I think it's the client thats the problem, I've never experienced anything like this before..

Can anyone please help me, because I have seriously much clothes I still want to wear on my avi but cant right now because of this bullshit.

Thanks in advance.
-- I can post some pictures of it later on.
