I completed Uncharted 3 back when it came out. Recently I got the itch to complete the fun parts again, but the game isn't recognizing/doesn't see my old profile/game saves. It just says "New game" when I click 'Campaign'. What could be the problem? I've tried redownloading the multiplayer pass and reinserting the disc, but nothing has helped. I can see my old profile in the Save data utility (PS3). Even the disc is the same, which rules out any region problems.
You can pick the chapter you like, change the dufficulty if you want to and play the chapter again. .
To jump in the middle of a chapter is not possible, i think.
