I don't think so..I don't have SP 1 or 2 to my knowledge, this windows xp is 4? years old now, and i havent updated it. Then again, It seems the servers are down or something so I dunno if i can truly play or not. But everything up to the Authenticating ID works
no my error is that once GameGuard finishes doing whatever its doing I get a japanese error saying that I need to turn off firewalls and virus protectors that might be interfering with the program....yet I have nothing of the sort installed. This is a fresh install of Windows XP.
