<p>Danny,<br>
did you resolve your issue? I am also having exact same issue on my D5200. I can take pics in Demo mode but memory card is not recognised. both memory cards are perfectly fine. I followed following instructions from Nikon but problem still remain.</p>
<p>1. Remove battery, Memory card, and lens for about 30 seconds<br /><br />2. Reinsert just the lens and the battery, power the camera on<br />ensure you are using an approved card: Answer Title: Approved SD cards for D5200 Answer Link: <a href="https://support.nikonusa.com/app/answers/detail/a_id/18424" target="_blank">https://support.nikonusa.com/app/answers/detail/a_id/18424</a><br /><br />3. The camera settings can be restored to default values by holding the "Menu" and "i" buttons down together for more than two seconds<br /><br />(these buttons are marked by a green dot). The information display turns off briefly while settings are reset.<br /><br />4. Hit the menu button and select custom setting menu<br /><br />5. Select "F" for controls and then "F4" labels " Slot empty release lock" <br /><br />6. Highlight "Enable release" <br /><br />7. Test camera with no card/ then reinsert the card and try again</p>
