[PS3] Error Loading Trophy Information

[GOAT]

So I moved in to my new dorm yesterday and I already have had a few issues with my PS3. The most recent is an error loading trophy information on various games. When I try to play AC4, I get a message saying "Registration of the trophy information could not be completed. The game will quit. (80022D11)" When I try to play Tekken Tag Tournament 2, it tries to load trophies and then gets stuck at 10% on the progress bar. I don't have an Internet connection for my PS3 either. If anybody has any ideas as how to fix this please!

Well you might need an internet connection to fix that error. :/

Yeah I went home to fix it, and I did they all work now, but I lost all my save game files and trophies in the process... :(
