Hello PlayStation community,
My cousin gave me his PS3. I created a new Sony account, and when I try to log in online in PS3 Network, it gives me a message that says "You cannot sign in using another user's sign-in ID (e-mail address)." What should I do? The PS3 is not brand new and has been used before.
Go to Account Management, Account Information and Sign-In ID. Be sure it's your email address that your account is associated with. If not, simply change the information (to a legitimate/actual email address).
