I have been using Configurable USB Loader version 56 for some time now with no problems. My system version is 4.2U. My cousin came over today and put in a game disc and it updated my Wii. Now, my Wii still says version 4.2U, but Configurable USB Loader just opens to a grey screen with a red power switch and sits there. Any help on how I can fix this problem is greatly appreciated.
