miis

Anytime when I try to open Mii installer on the Hombrew Channel,it just says "Error ret -1" Anyone know how to fix it?

So what I think I have found out based on my Wiimmfi friend rosters, is that if you add someone and they don't add you back, their mii will show up but it will always say that they're offline. I believe this is the case with Tim on my 4DR roster and MSX Sky on one of my other rosters.
