Deepsouthdeerjunky: Here are a few suggestions: 1)check your camera batteries with a digital meter. If any battery shows 1.0 to 1.2 volt, the camera will not function properly, or not at all. Even new batteries fresh out of the package may have a low or faulty one. 2)make sure your SD card size 2, 4, 8GB etc. is compatible with your camera. Format your card in the computer each time before using it. If a card is used in a digital camera, it has to be formatted. Something in the cards software or file system gets disrupted otherwise. I have been using Moultrie D55 IR and Moultrie M100 with great success. For cards I am using SanDisk, Adapta, Lexar and Verbatim. Kodak will work but not as good. My cards are all formattted and used in various camera makes as follows: SpyPoint IRB, Moultrie D55IR, 2009 model Bushnell Trophy Trail camera, Moultrie M100. My 2009 model Bushnell Trophy Trail camera lets me format the card in that camera. Regardless, all cards are formatted in my computer first.
Some members on various forums suggest using a certain card in a particular camera (marking the card for that camera). Good luck.
