I was playing this evening when the 64-bit client stopped working and the game screen went white. I tried to shut it down with the Control Panel but the Desktop screen flipped 90-degrees sideways on me and System Restore could find no recovery file. I rebooted in Safe Mode and was able to perform a restore and get everything back, but now I'm afraid to run the game again for fear the same thing will happen. This only came up after today's maintenance. Anyone else have this problem?
