not without regaining the original account information. You'll need to at least know the original email you set that account up with.
and I'd hardly think that an ASAP would be necessary for something like regaining an old user id that you clearly don't use anymore since you made a replacement.
I got a follow up question for you, unmei. I recently got a new PS3 and logged in and everything, but i wanna redownload my old games, like bionic commando: rearmed. I'm pretty sure i dont have to repay for it, but for some reason i cant find a way to get it back without rebuying it. am i missin something?
