You wont get any help... I have 3 accounts on my ps3 (two of them had the demo previously) and had to create the third one just to play the demo. If you had destiny demo on your account, I guess you cant use it to play it again. Try a new account. I just hope this problem is only for the demo and not the full game. I really dont want to spend a shitton of cash on a game that doesnt work.
