I was installing a WAD, then got an error. I got back to the Wii Menu and it says my Wii System Memory became full, so I deleted some channels and all but it still says that Blocks Free: 0. I tried deleting some more saves and channels but it still says that. I tried shutting and restarting the Wii and it says Wii Memory is full even though the channels were deleted! What do I do?
