I had this problem as well. I took the camera down and was about to return it. I discovered the card i put in had some kind of extra folder on it from another camera my friend uses. Just had to use a different card and it worked well. I have 2 M80s and like them well. Pretty dependable for a feeder but blurry pics on trails. I love the bushnell trophy cams 8.0, just wish they had the nite picture quality of the M80.
