Not sure, but you may want to just reinstall everything. What do you have on your system? Bootmii boot2? Cioscorp? Preloader? Modchip? If you want have a look at the 3-4.1 guide below and remod your wii, perhaps reinstalling hbc and such will workout your problems. If you have bootmii as boot2 you should make a nand backup before you do anything.
