Forum:Need serious help! Took save game from user to another user and cant save!

I need some serious help. Been playing in this save for about 30 hours, and changed from user to user because the PSN just got back up and i got a new ps3, and it says i cant save it and continue..! I have deleted the user that had it originally to try to play it in the other user, and formatting the hard disk and copying the save again on the ps3 but this happens every time! what can i do??
