I am not sure exactly when this problem occured first. I know that I sucesfully installed the latest CIOS, and this was pretty much the only major change I did to my Wii as far as I can tell. I realized the problem when I tried to install a forwarder WAD using WAD Manager. I received an error ret = -1 with no other specifics. I assumed it was a one-off, or a broken WAD. Surprisingly though, no other WAD installations work, even for WADs that have definately worked for me in the past. It is also seemingly hard to uninstall WADs, because I get the same error (though I have only tried uninstalling the 'corrupt' forwarder, and I don't want to uninstall any currently working WAD out of fear I may be losing functionality that I can't replace). Can anyone help me? I suspect CIOS here, but then again I don't understand why this happened. Any help for a solution? I have a full NAND dump, but I have a fear that it might have been taken just few minutes AFTER the installation of CIOS, and the other working back-up was taken several months ago so it would not be much help.
