I have same problem here, the game installed correctly. Then when I start, the mouse cursor didnt appear, but if I move the mouse different in areas I see the buttons highlight.
I have a Amd Phenom 9550,
2GB RAM DDR2
Windows Vista 32-bit
I already downloaded 1.05 patch and have the latest driver for my ATI Radeon HD 3870, I downloaded Catalyst 8.1 and the problem still occurs.
and when I start playing a new game, even with the invisible cursor, all the space near the planets and Stars are Blank.
and I tryed compatibility mode too but no luck.
thanks.
