I can only guess what mean by "memory slot problem" because you have not given any details, so I can only give you general information. If your problem is that your SD card does not work, I would suggest you start by reformatting the card in the camera. First, make sure that your SC card is not write protected. Hold the SD card so that you are looking at the label with the angled corner on the right top. Look along the left edge of the card and you will see a slider switch. It is very small so look closely. On most cards, there is an arrow on the label pointing downward with the notation "Lock". If the switch is in the lock position, slide it all the way up to allow you to send information to the card and replace the card in the camera. SD cards formatted in a computer often do not work because the camera's format function writes slightly different encoding to the card. Push the Menu button on the left side of the camera's back (just below the top button) and scroll to the Setup Menu and Format Memory Card. A warning message will be displayed. Use the up switch to select "yes" and push the center OK button.
