The worst thing happened to me today, I was playing some flash games on my homebrew enabled psp, when I came back to the menu however, all my games, pictures, movies and pretty much everything else were not there. When I went back to the internet section all my history was not there as well. I checked my memory stick on my pc and I noticed that the memory was "full" even though I see no files on it. Can someone please tell me what's wrong with my psp? I don't want to format it because I had some important stuff on it.
