sd card section on "wii channels" freezing

So I installed the bannerbomb again after my homebrew channel messed up and I needed to reinstall. So I did that but now the SD card section freezes? I want this section to work if I ever want to move channels to that area. Can someone help?

Delete bannerbomb from your SD card. I think it's something like /private/ATKN/data.bin. Just delete the whole "ATKN" folder. If you made the "private" folder just for bannerbomb, or renamed the existing "private" folder to something like "privateold", you can delete the current "private" folder and restore the "privateold" folder (if you have one) and then data management and the SD menu will work again as normal.

thanks! that fixed it
