Whenever we try to start the mii channel, we get a black screen with white text saying ' mii channel system files are corrupted. Please refer to the wii operations manual for help troubleshooting. Press the A button to return to the wii menu '. This started about a week after the system was new, and has been this way for weeks.
It apparently doesn't affect gameplay, we just can't do anything as far as miis.
If this is the wrong forum for this, I apologize in advance. Thanks for any ideas.
