i got my ps3 a few days ago. i never signed up for a playstation network. i have wireless internet for comcast. i used my WPA key to access the internet setting thing. and it said i am now able to get internet access wireless. i then succesfully clicked on sign up for playstation network. once i was on it i had the 2 options. i could either sign up for a new account or use a already used one. i clicked the new one option and immediatly it said ” error 8120710″ or something like that. i even clicked on sign up using a used account and it said the same thing. i think i got internet access but for some reason i can simply not make an account. what is happening and how do i fix this error?
p.s. i updated the internet system and it still wont work
