Every Viewer.. Catznip, the SL Viewer and Singularity... All of them crash just as soon as I press login... Idk what to do.. It worked on Windows Vista SP2 64bit but on Windows XP SP3 64bit this is what's been happening.. Specs: AMD Phenom II X6 1090T @ 4.5ghz G.Skill Ripjaws 1333mhz 8gb HIS Radeon HD 5750 1GB GDDR5 Superclocked 1ghz core 1500mhz memory. Any suggestions? I installed all the C++ Redrist, DirectX, I also have all the .net frameworks, latest graphic card drivers.. Pretty much went through everything.. -w-; Halp.
