Just got the game today, upgraded to 1.2 by downloading the patch from the website and installing. I've got my colors set to 32 bit instead of 16, I just downloaded new drivers, catalyst 6.6 or something, from the ATI website. Before doing that I couldn't even start a game. Now, I can start the game, but it randomly crashes, in this case while I was looking at my homeworld screen, before I had ended my fist turn.

Here's the debug.err:
