Ok, so I turned on my wii after a month or so of not using it. I wanted to install the usb 2.0 thing. Ok so I turned on my wii when my brother wanted to try out this new game ok whatever. Then I told him about preloader. I shut off the wii, turned it back on, held the reset button and there it was, the preloader menu. From there I chose to go to the system menu. When I go there however, ALL installed channels are gone. All I had were the news, photo, weather, internet disc, and homebrew channel. What I want to know is why did this happen? All channels and saves were gone.
