DLC does not work on pirates (Total War: Rome 2)

Guys, I need your help. I downloaded a pirate from a torrent with DLC and all the patches, but when I start the game I can not play for the factions that add these DLCs and when I try to start the story campaign "Hannibal at the Gates" and "Caesar in Gaul," the tablet crashes total war rome 2 stopped working. I don’t know what it is.
