Update your password
NOTE: Please do not click the “Forgot your password” button multiple times as this will send a new email request to Sony per press. The system will lock you out for a rolling 24 hour period after the third request. Due to the high volume of password reset requests, there may be a delay between pressing the “Forgot your password” button and receiving the password reset email so please be patient. If you have pressed the “Forgot your password” button multiple times, use the temporary reset link from the LAST email you receive from Sony as it will contain the current and only valid link.

On the PS3, you will be prompted to update to the latest system software. After you update, enter your Sign-In ID and password you will be prompted to change your password. If your account isn't activated with your system (never downloaded anything using this system), an email will be sent with instructions on how to reset your password. Please note that due to high traffic volume following the restoration of some PSN services, it may take up to 24 hours to receive a password reset email.
Activarea contului se face din "Account manager" de pe consola. Eu am facut asta dupa ce am schimbat hardul pentru ca nu ma lasa sa joc ce descarcasem de pe celelalte conturi(de US si UK)... Exista acolo activare pentru Movie si activare pentru Games.... ceva de genu'

I provided a fake email address, birthday, and or other identifying information and don't remember it
