Micro SD for base station not detected

Put 16 Gb card into the base station. Did a format. When I check CAM Outdoor I can flip the app switch to backup to the base station as if all is OK. But now the base station keeps saying there is no card in it and I cannot access the card. Nor can I playback from the camera. Any ideas? ACTUALLY NO PROBLEM-JUST TOOK ABOUT A HALF HOUR BEFORE IT FOUND THE CARD
