First: don't double post. It's against our forum rules that you had accepted.
Second, your mod is old. We don't support other modding methods besides our own, so start off with modding your system using our guide, Softmod Any Wii, which is linked in my signature.
Don't format, delete, or attempt to undo anything. Just follow the mod from the top down and it will overwrite everything that matters to get it to our standards.
Then if there are still any problems that needs to be addressed, we can look at them after your system is current.
