I purchased a M series D-40i camera package and it has worked well up to this point but now it will not take any pictures. It is about one-year-old I believe. You can turn the camera on and everything functions properly to the point where the little timer goes off where it should start taking pictures. At that Point it says 002 days or 013 days and shuts off. I have tried multiple cards and batteries and still get the same results. Any ideas what is causing it to give me this message and shut off?
