i downloaded GT5 prologue full game and installed on my PS3, it was installed coreectly but i can't run it, my PS3 say either: log into Playstation network or you don't have the right to run the game that means the person you uploaded the game here should share his acc an we could play the game.

does anybody maybe know how to pass the game blockade? to get into the game and to delete the info which give the game the acc?
