Had to factory reset my brothers PS4 because of a corrupted Mortal Kombat Save (I put the disc in before the reset and it would come up as Corrupted data file until I ejected it) and now it won't let him play MKX online. He has PS+, d/l PS+ games, play other games online and the kombat pack works just fine, it's only Mortal Kombat. I've tried deleting the game and reinstalling it, waiting until it said everything was completely downloaded yet nothing seems to be working. The disc is perfectly clean, no scratches or smudges either.
