I put in a brand new SB card and camera says "memory card error" "memory card locked". It did the same with the card I had used in it previously. The menu has no "format" line, instead, where format should be, it is blank and when I arrow down to it, it skips over the blank. I have tried 'reset' and still nothing. Both my old card and the new card work in my other camera. I have tried reset on the menu, but no change. Yes, I have moved the switch on the memory card. Since the last time I used the camera, it has been sitting in its case. It has new batteries. HELP!
