is this a digital copy(downloaded of playstation store) or a hard copy(UMD).if its a UMD then go to the playstation store go to the top left corner and there should be an icon that says redeem code.click on that and type in the code on the ftb3 owners manual thing(the code is on the top on the back) then exit out of the playstation store pull up ftb3 and it should work.thats what i had to do.if its a digital copy im not sure what to do...hope i helped
