So I have a copy of Uncharted: The Nathan Drake Collection here. It worked find a year ago when I played through the games yet now it wont work at all. Every other game reads perfectly fine. I have tried Deleting the game off my harddrive, rebuilding system database, wiping disc with damp cloth from the center outward, and many other things. I just cant figure out whats wrong with it. There is not a single scratch on it and it worked find not long ago. Any ideas?
