Oh buddy that doesn't sound too good. So i guess you didn't follow one of the guides here and are now madly trying to find a life line here at Wiihacks.
If I'm not mistaken your first post here at Wiihacks should have been in the introduction section (saying hey whats up I am new here , for example ), then search the forums for answers, if an answer still isn't found then Post a question. I will leave your fate to the Mod's lol
I am sure there is a similar case and lots of information about NAD back ups some where on the site.
