i have a Chiiped wii firmware 1.4E with the wiikey2 chip and i can not get the usb loader channel to load,,

i have read countless tutorials and downloaded diffrent version from 1.0-1.5 and i can not get any of them to install

every time i try running the cios installer that all the tuts say i must have installed,, it says patching,, a few times,, then it says error and bombs out,

i have tried installing the usb loaders,, i have tried the twighlight hack way and through the wad manager through the homebrew channel,, but its not working...

to be honest its doing my head in so any help would be fantastic
