Hi everybody, i have a problem. I just changed my windows 7 to win8 and i have to install again my second life viewer. But everytime i open it, it says that my video card driver did not install properly or out of date. I'm really innocent when it comes to installations or hardwares. How can i update or reinstall this driver? i can't even find it on my program. I aleady miss playing in SL. Help
