Initially had ver 4.2U and it was soft moded with HBC and also had USB loader GX. Upgraded via Nintendo trying to access Wii Shop Channel. Used the Smash Bros. guide to get to LoadMii via stage builder. Now stuck at LoadMii. Everytime I try to run MMM it says unplug expansion pack on Wii mote. No mater what I click, connect, or disconnect on the mote. PLz help.
