thx

I got two blue screens of death yesterday, after I downloaded the 1.20 client. I really hope it isn't the client, but if it is that poses big problems.

My graphics card is the NVidea 8500 GT 1GB =/

I too have a problem with my Second life update. I have not received any error messages but now my avatar is all distorted as is everyone else s avatars but all my surrounds look completely normal. How can I fix my view of the avatars? everyone else say they see my character normally.
