Ahh Kill it!!!!
Anyways, I've got this problem. Since I know you guys love asking questions, and it's good to reproduce steps and be detailed here I go.
First of all, I have the Beta 2 patch installed. I join any server on any map, there seems to be no pattern so far, I've tried four times. After joining the server, the game will crash, the last 1 seconds of sound will loop and the windows will register the game as still running. The game crashes at any time. Once in the ready room, and 3 times while PLAYING. It hasn't crashed while in specate, so I don't know if it's a rendering problem.
Really, thats all I can remember. I'm **** tired, forgive me. I work over at GameAura.com which is SUPPOSED to be a mirror for the sites, but right now the servers are acting up and we should be getting upgraded dedicated machines that have a bigger pipe soon. So hopefully we'll have a good mirror, not as good as redphive, but still good.
