Sorry for the late... reponse. But I've just encountered this problem for the first time.
Whenever I startup the game, and load my profile, everythings alright. But when I select a planet, whether it's Instant action, Training, space battle or whatsoever, the game exits to my desktop.
I've tried all of the above, but it's still not fixed, unfortunately. I'm using Vista. I would love any help.
