is it normal for the DS to start having trouble reading my acekard2i? It reads just fine most of the time but recently it's been unable to read the cart, and it says that no DS card is inserted even though it is in. I take the cart out and blow in it and in the DS Slot and it works after I do that, but I also have been experiencing some random freezing. It only happened twice so far, once while playing The Sims 3 and again while Bookworm was loading up....
