It seems that your memory card may have been corrupted. In this case I'd suggest that you back up your files that are on the card and then format the memory card. Hope this will help you to solve your problem.

• Fully Corrupt:
  When the entire save area of the Memory Card becomes corrupt, the system will inform the player that the Memory Card is corrupt and offer to format it. The card must be formatted before gameplay begins or when the game attempts to access the Memory Card. The exact message may vary from software to software.
  Follow the steps for formatting a memory card.

  Suggestion: It is always a good idea to copy your most important files to a second Memory Card as a back-up.
  

• Data Area Only Corrupt:
  When only the data area of a Memory Card is corrupt (not the entire Memory Card) the game may not detect this until the Memory Card is accessed. Once it is accessed, the game will inform the player that the file being accessed is corrupt and must be erased. The game will only delete the one file being accessed and will not format the entire Memory Card (Other saved game files on the Memory Card may be OK).
  Follow the steps for deleting a file.

The system may attempt to format the card, but if it cannot it will give the error Memory Card is Damaged. There is no way to recover the game data from the memory card.

2. Use the Control Stick to select "YES" and press the A Button
3. A window will appear to notify you that all data will be erased and ask again for confirmation for formatting.
4. Use the Control Stick to select "YES" and press the A Button.
