Please provide any additional information below.
deleting the channels doesn't work ether. the logs say something about invalid directories and files "does not exist". installing too many channels causes the emulated nand to "fill up." I have over 99 GB free space on the file system with the user dir, so i don't think it's full. without the ability to delete channels via wii menu or the game list, you get stuck in the Data management screen and the system menu won't work. i.e the nand has to have space available or it won't let you out of the Data Management screen. the only way to fix it is to delete the data out of the User/Wii dir, using the host os.
