HELP!

I have a LMS 522C. The problem I have is I cannot save my data to another card. When I remove my lake map chip the lake map stays on the DF even with the chip removed. Even when powering down and back up the lake map data is still in the DF WITHOUT a card inserted. And the empty cards (I have 2-4 gig cards that says they have 44% free space and I KNOW they are empty...it's the lake map card which has 44% free space and the DF still remembering and report that free space instead of reading my empty cards.) After I insert a blank card and hit the button to go to the transfer data screen a pop-up comes up telling me to insert a MMC card. I do not believe the lake map data is supposed to stay on the DF after I remove the chip. It should go back to the blaock strle picture screen that the DF came with. Does anyone know what I am going to have to do in order to save my data on another card?
