I've been using wiiflow for a long time now and haven't had any problems. The other night I turned on the wii, loaded up wiiflow, it recognized the hdd and all the games, but whenever I go to play one it just boots to a black screen and I have to turn the wii off then back on again. I've tried multiple loaders all with the same results. I have 4.1u firmware installed. The last thing I remember doing before this happened was going into the weather channel and changed the location. Any ideas one what to do?
