I’m trying to register my ps3 on their website. On the website there are three boxes where you type in the serial number, but on the ps3 the code has no spaces at all, but is separated from the CECH number. I’ve tried many times but I cant figure out how many characters go in each box. It always says, ‘serial number invalid, please try again’. Also, my CECH number is not on the list (CECHLO1) so I chose CECHLO2. Just wondered if that was a problem too. 10 pts. first helpful answer.
