I have been working on installing all my games onto my harddrive. Everything worked except for Twilight Princess. It gets to 72% then the screen jumps and if I hit any buttons, it says that the game installed succesfully, when I try to run it, the wii freezes. I have tried both USB Loader GX and wiiflow with the same result. The only thing I can think of it that it is the disc itself, but the disc doesn't look damaged. Any idea?
