I installed the game, played for about 30 minutes and thoroughly enjoyed the expansion/beta. I alt-tabbed while it was maximized, then tried to alt-tab back into game, I couldn't get video back (still could heard the audio from the game). I ctrl-alt-del and force quit the game. Even after a computer restart, the game doesn't get past the first 'Loading' screen, it crashes about 5 seconds after launching it.
