I downloaded the demo version yesterday to give the game a try and I really like it and would like to buy it but It keeps crashing. It seems quite random. It happens about every 10-15 mins and I cannot figure out what the problem is... It crashes only in response to me clicking something. If i leave it alone it seems to be fine. However its never the same button twice that causes it to crash

I could cope with this but whenever it happens all my savegames seem to be ruined. Whenever i try load them after a crash It simply finihes loading then quits to desktop.
Oh and my ships seem to be messed up. There are no textures on the models they are all just whatever colour my races base colour is. This leads me to think its a video card problem of some sort.
Help anyone?
The debug is after trying to load a save game after a crash. ill try post one of what it says after a crash from ingame.
