Autolog error 193

Back a long time ago my friend downloaded the demo for Need For Speed Most Wanted. We used my origin account because he did not have one. Me and him got the game for christmas and I signed it my account on my ps3 and it let me in but it says an account has been found (mine) and it wants to sign in to mine on his. Gives him error 103. We deleted everything on his ps3 that said most wanted but it still didn't work. Any way to fix this?
