Downgrading you risk the chance of bricking your wii, that would get you back to a clean system, although i recommend you download softmii 3.0 instead if you do plan on reinstalling your system menu, the old softmii only has the option to install up to 3.2 i believe, the newer one has 4.0, you'll have to use wain's updater to get to 4.1. I would try what i suggested first, i believe its one of the hacks in preloader, i had the problem myself, sounds like your successfully modded, you just need to get that issue squared away.
