R41 - having an error on micro SD card

Out of nowhere my R4i says "System date error. Please check NDS system date".
Tried another R4i and SD card. Worked fine. Tried SD card B on original R4i. Worked fine.
So theres an issue with the data on the Micro SD card. Any suggestions how to correct???
Thanks :-\

either back up and format ur SD card or
find the latest firmware/kernal for ur R4hope it helps atleast a bit

Deviluchiha - ;) Thanks. Took a little time, but That worked. ;D
