Supercard mini SD not working.

My Supercard mini SD was working fine for the first day I had it but today I turned it on and everything but the top option was in some Asian language and now after I plugged it in and out the card isn't showing up. My slot 2 is working and the card won't show up in any other DS. It has the latest firmware. Help please?

Try backing up, reformat your SD, and then reinstall the latest firmware.
