M3 sakura problem

I got a problem with my m3i zero card with sakura version 4.8 i played a game and my card got stuck so i restart my ds and then i get the error:
critical error! the displayed size and the real size is different
fixing method:copy all data to the hard drive fromat the card encopy everything backapplication stoppedHow do i solve this i dont know how to format my card.Please help!

Copy all files to the computer first.Then do this: Open (My) Computer > Right click your micro SD card (detected as Removable Device) > Select Format.In File System select FAT32, if available, else select either FAT or FAT16.
Then click "Start" & "Yes" or "OK".

F*** Sorry for that but now i've tried to play a game the loading took long so i restarted it and now i get the same stupid error! :(
