Hey, I just got my son NBA 2K on Sun. For some reason it won't let him get online and he can't do the extra features like building court, etc.. Gamestop don't know how to help and Microsoft couldn't fix it. 2K only has a site where u can submit a request and I have done this twice. Does anyone know if we r doing something wrong or what. All of r other games work perfectly fine. It has to be something in the system we have to change or something,, driving us crazy!! Thanks for any help!!
