Not quite sure. You aren't being very descriptive at all. I would try deleting your "Game Data", NOT your GAME SAVE, your "GAME DATA" for Uncharted 3. Then when you load the game up you will have to redownload the install and update and that should work. If it doesn't then I would check the disc for scratches. Hope this helps. Uncharted 3 is a GREAT game. That was my 2nd platinum trophy right there! Happy Gaming.
