After a toooooooon of frustration I finally got a card to work on it. When I first got it home I only had a few smaller cards around the house (less than 1gb). I read on the package that it was 1gb-32gb.. So I just went ahead and got one of my 2gb cards from our cabin and tried it. Still didn't work. But I just got home and formatted that 2gb one and now it is working. Thanks for the tips!
