When I first started up my Wii today, it told me it was unable to open the Mii data because it was corrupted. While odd, I didn't think it was a real issue. I started up Zelda Cross Bow Training or whatever it's called... and then it told me I couldn't load my files because the Mii data was corrupted. It told me to go to the Mii channel. I went over there and it told me the data was all corrupted and offered the option to reformat the memory on the Wii. But... that would mean I'd loose everything. I'd have to set up all my friend codes again... I'd have to restart all my games... etc. So I chose not to reformat the memory. But I still can't play most of my games because most of them require Mii's for the load game icon if nothing else. Googling the error message it gave, I found that Nintendo will offer to repair it under warranty... but I'm no longer covered by that. So what does anyone think I should do?
