Hi, I have just purchased a Fujifilm finepix s4000. After inserting batteries and SD card for the first time the camera would not allow me to complete set-up and a warning 'PROTECTED CARD' came onto the screen. I have replaced the SD card and ensured that the switch is not in the lock position, but the problem still exists. If I remove the SD card I can use the menu,zoom etc., but when I replace the SD card, none of the functions work and the warning comes back on screen. Any help would be much appreciated.
