Hi. My Wii freezes on a black screen every time, just as the first level of bit.trip runner is about to begin, and I have to turn off the power to get it back. I've tried redownloading the game from the shop a few times, and i've tried downloading an ntsc and pal wad. I'm on firmware 4.2u and every other game that I've tried, wiiware or otherwise, has worked perfectly. Anyone have any ideas?
