I'm not very good at this whole hacking thing, so bear with me if what I did was pretty stupid.

I have a 3.2U wii with wiikey 1. I put usb loader gx on it to play galaxy 2 a week ago. today I installed patchmii and dvdx on it to play dvd's on it, but when I load usb loader now a black screen and a lot of code flashes on the screen and then my wii freezes. everything else still works, except this. can anyone tell me how to get usb loader to work again? I don't care about getting dvds to play on the wii, I just want to revert my wii to how it was before i installed patchmii and dvdx.
