Professor Layton and the Curious Village

Hi, i hope someone can help me.. i've DL'd this game, and it starts to load, goes through the screens thay say 'level 5'.. then 'mobil clip'... then i get a white box that says 'save data has been corrupted and will be erased. Please tap the touch screen'. So, tap the touch screen, then it just goes blank.The game is on Nintendo DS.. and my card is Model M3-DSR-EUR/USA+Any help appreciated.. xxx
