I got this problem every time I try to install a wad. file. It says:

ERROR! (ret = -1022)

I have used lots of different WAD Manager-versions and none of them work. I have Homebrew Channel 1.0.2, and something more...IOS61 v19.26. My Wii is on version 4.0E and I don't have a modchip or anything like that....Plz help I'm really stupid I know
