My bushnell trophy cam does not take pictures in

my bushnell trophy cam does not take pictures in the camera mode.The video mode works wonderfully, I tried all kinds of ways and found that it does work when connected to TV.When switching to camera mode and try to take the "shot" the camera control buttons freeze up and I have to restart it.I have formated card and am using a SD 2gb Dane-elec card. Any help would be appreciated.
