You dont sound stupid, if problem were easy we'd all be happy!
The thing is when you mod the Wii, the hacks stay in the memory even if you delete channels the hacks are still there thats why everything we've been trying isnt working so far, the hack is still telling your wii its PAL. So the 3.2 install I'm telling you about in the anyregionchanger will re-install your mod on the proper fw and should overwrite the pal values completely. So when I say "redoing" I mean starting from the initial hack, so say you do the hack all over again, this time just make sure you pick the right fw or let AnyregionChanger 1.1b mod05a install that special 3.2 menu for you and it should clean up the conflict on your system.
On a Wii I worked on a few weeks ago I was installing softmii and using AnyregionChanger 1.1b mod05a is part of the process, once I ran that 3.2 install it fixed the mismatch. I'm hoping it will do the same for you.
