HAS ANYONE HAD THIS PROBLEM WITH A MOULTRIE FEEDER BEFOR? EVERY CARD I PUT IN IT IT SAYS THIS. AND THE CARDS ARE NOT LOCKED. THANKS BRONCO2

I think that there is a slide lock on the side of the card itself, just look at the card and if it has the slide move it up or down and try it in the camera see which position works.. I think it even tells you on the card the locked and unlocked position.. Good luck.
