I've just started with SL. I have updated my video card drivers to version 13.1 (my graphics card is AMD Radeon HD 7970), I have tried Firestorm viewer, I have uninstalled and reinstalled and it hasn't been fixed. The problem is that I open the viewer and all it displays is a white screen or a black screen. I can also only close the viewer from Task Manager once it is opened. Any known fixes for this? I am running on Windows 7 64 bit Thanks
