After formatting my computer and install the new WinXP Service Pack2, I get into deathstarbattle zone to play and the screen is half black. I done the "window firewall" as people are having problems using the new WinXP Service Pack2 but it still gives me a problem of the "half black screen". Hopefully is not my video card problem because if it is, I don't want to waste money to buy another one. I hope there are some other reasons to the problem I have right now. Please reply this urgent message as soon as possible. Thank you!
