I decided to play uncharted again to get some trophies. I popped in the disc and waited for the new install to complete. Once it was finished it just hanged on the loading screen. It was then I decided to re format my ps3. So I did the full reformat which took about 3 hours. That managed to do the trick, the game was up and running and I managed to get a couple trophies. However, once I got up to 60% completion, the same problem came up and I was once again stuck on the loading screen. I did a quick reformat this time, but it didn't work. Now the loading screen won't even show up, its just stuck on a black screen. Can anyone tell me what the problem could be?
