Im not a real tech guru, but this is what I would do. First make sure that the little slider on the side of the card is not in ‘lock’ position and that it is less that 2GB (Cudde says 2 or less for captures). Put it in computer and delete every thing off of it. I would then format the cam and card. The instructions for this are clearly labeled on the top of page 5 of this link.

If that doesn’t work. I would then try running the camera without the card. Turn cam on without card, make it take some pics, then turn cam off, insert card and turn cam on, wait for green light (next to card) to stop blinking, turn cam off, check to see if pics are on card.
If none of this works, Id bring it to where I bought it or send it to cudde. If they wont take care of it Id fill it with 3″ #2 Federals and buy what has worked for you in past
All kidding aside, I have never had problems with my cuddebacks. The very first one that I bought with IR and video just dumped on me, wanna say its 8 years old or so, left out year round.
