I have a Nikon Coolpix S220 woth a 4GB card. I cant seem to get the pictures off of the camera and onto my computer. I have done this easily before, using the USB cord. I have a Mac and they have easily uploaded before on a Mac and PC using this method. Now, my Mac won't recognize the camera, or that even anything is plugeed in. Also, the PC freezes when I click on the camera to view my pictures. I've also tried just inserting the SD card into the hard drive, but the sam thing happens! HELP!
