hey guys, trying to troubleshoot a problem I'm having on a digital camera. It works perfectly except won't take pictures....any ideas?? -the shutter works, -the mem card is fine, -I did reformat it, -it switches between modes correctly, -it did not get wet! When I press focus to take a picture, an icon comes of it looks like of offset, stacked photos (squares really) with a red "X" over the top of them. Any ideas??
