I have had a small problem uploading projects to the card. About half of the time, when I try to upload a project, I get an error message stating that the project can't be written because the card is damaged. I then remove and replace the card and try again. It takes two or three tries and the project will finally write. Has anyone else had this problem? I'm wondering if the card is actually damaged or if it's a program glitch. Thanks to anyone who can help.
