I was using my old test PSN account with my PS3 for a while, but would like to change to a new PSN account, due to a normal online ID.
So I created a new PSN account.
Now I would like to use this new account on my PS3, so I go to account management, and insert the new email address id after giving the correct (old) password. However the PS3 keeps telling me that the input of the email address is not valid! However I have no problem (usually) logging in with the account on the PC, such as for logging in to this message board.
What is the PS3 complaining about?
