Can't get SD card to work

[JordRB]

I don't know what's wrong. I can't get my Riivolution to work and my Wii runs an error when I try to read my SD card. I thought I'd to redo the whole thing, clear the card (put the original files in a .zip and store them on my computer) and see if I can't reinstall the Hackmii and bannerbomb stuff, but I still get the error.

Can anyone help me?
