Hello my language is Spanish, use translator. I have the same problem from today July 11, 2013. sl to enter, I get a message from Nvidia and OpenGL, not understanding anything, is in English, my card is NVIDIA GeForce 7050 PV nForce 630a Nvidia, and my avatar looks into squares of all colors, and the landscape gets all black and then in multiple colors and lightning, a disaster. Try Nirans, Catznip, Sl, etc etc and all alike. Anyone can bring something good to resolve this? I'd be very grateful.
