I have had my ps3 for a few months (320g mw3 bundle) and one day while I was playing mw3, I rage quit and turned off my ps3 mid game. now whenever I click x on mw3 on the home screen, my screen goes black like it is going to load, then just goes back to homescreen. it only does this with this particular game. I borrowed my friend's disk of mw3 and it didnt work. help!
