OK So when I installed the newest SL Viewer on my Windows 8, it worked fine for months. I even have it on my Laptop Windows 8. Now after I update to a premium account and attempt to logon, it says Checking hardware and making attempt 1 to server and then it vanishes completely. I can use the singularity version fine but I would like to have this work. Anyone have any ideas what to check?
