I'm having a similar problem to nick. I just downloaded the .91 clone wars mod, have the 1.1 homeworld update and the latest drivers for my x700 and every play mode except reinforcements crashes when it finishes loading. When I play reinforcements it loads the map but then says your fleet is victorious as soon as it's done loading. I've solved the problem when it does load, it didn't like it when I left the AI on random. So I changed that and now at least I can play a few modes.
