I am trying to run SL on windows 7 64-bit Home Premium edition with an NVidia GForce GTS 250 graphics card and my drivers up to date. Whenever I log in my avatar is completely black and my face is missing. I've tried the things on the little wiki site and they didn't work. I'm not sure if I messed seomthing up because it worked for about 5-10 minutes when I installed it before I started messing with my appearance. So is there a way to reset everything to default and if that's not the issue does anyone have any advice?
