My older brother seems to be having a slight problem with his Lego Star Wars Original Saga PSP game. On Empire Strikes Back chapter 5, he is unable to get to one of the minikit canisters due to some sort of glitch. In the steam room where you fight Vader, there's a grill for small characters that simple will not open under any circumstances. We've tried everything, including swapping the disk for a new one, no joy. Please advise as it's driving him crackers being unable to finish his fave game, and driving me crackers having to listen to him bitching about it.
