There is 2 way of downloading a game once is the Retail version (BLES, BLUS etc..) and the other one wich you probably did is the psn store version (NPUB,NPEB etc..) .My advise is to download a disc version otherwise youll need to be more experienced since its needed a fix to run a game with dlc's or black screen will come up. Dont think to go online with it or you'll end up banned in no time, unless you get more experienced as i said and know the right app to use.
BY THE WAY IS FORBIDDEN to use or download pirate stuff and we dont encourage people to do so, be advised.
