Try the procedure of changing drive letter on the SD Card. When it pops up in the box and it says "moultrie" and then a drive letter delete Moultrie it should be highlighted. Then click on Format under that same menu and restore default. My camera wasn't working and done this and it went to working. And it was a Moultrie card. If your not pretty good a technical things be sure to pick the SD card when it pops up and not any of the computer drives. If I can help anymore let me know. Good luck.
