I had this error also. Camera wasn't flashing (I-40). Moultrie first had me cover the day/nite sensor during diagnostic test, they said this should fix it. It didn't. On my second call to Moultrie, one of the technicians said "send it back to Cabela's, oh wait, have you tried the download? I hadn't. Go to their website, look up your camera, find the software update link, download it (follow their instructions). Even though I had the latest software version, after reloading it, and then powering down, Whallaa! it worked! Just a reboot I guess, anyway better than sending it back. Hope this helps someone.
