I have installed the SL viewer on 2 computers. Laptop SL viewer is working fine. Than I installed it on my newly upgraded with AMD video card, & installed version 3 of SL. SL viewer worked for 1 day & than the next day I started it again, I am stuck on the loading screen where the progress bar comes up & it shows the world scene area/zone loading up status, & it doesn't do anything. IT is totally stuck: -tried to runas admin -uninstalled / re-installed -downloaded newer SL v3 viewer & installed -upgraded my video card drivers -checked for any other driver fixes -rebooted several times. Same result, any help appreciated?
