You aren't using an ios with a trucha bug when you're running wad manager.
3.2 is so old I can't remember what you have to do & where you'd find the relevant files to do it, it might be enough to use the ios236 installer & then use multi mod manager to install the wad.
However softchip is also ancient.

Unless you want to boot out of region games through the disc channel or it's a modded korean wii, then I'd install the latest homebrew channel & upgrade online to 4.3. Then use the ios236 installer & mmm. I'm not sure I'd bother with softchip though.
