This happened to someone a while ago..

It seems it was one of 2 things.
1 thing to try.
Make sure that your stick is assigned as controller 1 before you press start at the title screen.
1 other thing to try. If you have a 2nd user on your PS3, try it on that profile.
If the hanger works then you have a corrupt save file.
