I put mario kart Wii into my Wii, and decided to go onto the mii channel. However, when I loaded the channel, it came up with a black screen, saying " the Wii system files are corrupt. Refer to the Wii operations guide for troubleshooting" so I reststarted the Wii (by pressing the power button) everything was fine! Does anybody know exactly what happened? I think it was some sort of clash between the disc loading and the mii channel loading, but I'm not sure.
