maybe you don't have a cIOS then get one
use the softmod any wii guide (link below)
edit: no need to worry, follow the guide step by step, it will correct everything you messed up
it will give your wii brick protection and you'll get a nand backup (your wii memory) so you ll be able to restore your wii to that state even if you screwed something up
do a little further reading (on this site here..) ultimate index (link below) helps a lot, guess you don't know exactly what a cIOS is right now..
