i havent played my ds for some time now. However i picked it up this morning thinking id have a play though spirit tracks again at work. now i think something must hae been spilled on it the card slot is all sticky and the cards wont read. does anyone know anything i could try to fix it or am i in for a boring day at work.

Well since its not reading cards I think the best bet would be to send it into Nintendo for repairs would be the safest bet.
