Yeah I'm having issues with one of mine too [:@][:@]. I have a couple Moultrie Gamewatcher 2.1's. One of them works fine the other one is giving me fits. I set them out at two locations that "should have" had similar deer activity. One week later I had over 40 pics with one of them and 2 (me testing it) on the one in question. The one that doesn't seem to be working I set up and tested it by walking in front of it twice. It seemed to work fine. I came back, walked in front of it again and nothing. I got within 5 feet of it and NOTHING!! So it was out there for a week not detecting anything. That was the second time it's happened with this camera.
