Although I can not make the random crashes come at will, I can make them come at the start, just by using "Play with SIX" Game launcher. About 1 out of 6 or 7 tried works... Also running right from the Steam library crashes a lot more then just clicking on the icon on the desktop (although that crashes too)
I do get freeze ups in game as well that lead to crashing sometimes but if I wait long enough the game usually comes back or kicked out to the lobby...
