I just bought a Playstation 4 yesterday and upgraded the game to the PS4 version. I wish I had looked at these forums first. The game ran just fine on my PS3, and now I'm having the same problem all of you are. Error 2002, error 90K, error 10105... I can't play at all now. From what I've seen around here, this problem has been here for close to two months now with no real resolution.
Square Enix, please... you've gained back so much of my respect lately. Don't lose it now by leaving us out in the cold...
