Entrenchment crashing

I just Downloaded Entrenchment here, and started playing it. In game I tried adjusting the resilution and when it switched, the screen went black for 20 seconds or so and then switched back asking if i wanted to keep the new setting. I pressed cancel and resumed the game with old settings. The first thing I noticed was that the sun was blacked out, then just a few seconds later entrenchment crashed.

I started a new game. Played for about 40 minutes and started to build a star base and then it crashed again. Something is up with the graphics.

I am using an ATI Radion HD 2400 [Dell E228WFP]

My computer specs:Dell Dimension DXC061, Intel core 2 CPU, 6700 @ 2.66GHz X 2, 3 Gigs of ram, 32 bit Opp. Running Vista Home Premium.

I have not tried anything myself yet. Anyone having the same issues that might know what I could do to resolve this you input would be greatly appretiated.

Thanks.
