It might work better if you follow the softmod any wii guide. This is the best guide and easy to follow. It only takes about a half hour or so, and that is with reading it twice first. It's actually the safer way to go. The link is in the spoiler below.
I don't really recommend removing your softmod but there is a guide here. But really it will take you just as long as fixing your existing softmod and less risk of bricking in the process.
