I got a backup from The Force Unleashed Ultimate Sith Edition from a friend a while back. Everything worked fine but now I wanted to do the Hoth mission and it's just stays at the loading screen. I had this to when I wanted to start the last challenge (Force Repulse I think) and I can't do them. Everything else is working fine except those two things don't start. Anybody got any ideas what's wrong? I already removed game data and it reinstalled it but still doesn't work.
