Hi. I have had consistent ease of use on this camera for a long time. Yesterday, I was shooting with a new Godox 685, alkaline batteries. Getting some very nice images. It just stopped shooting, saying the card was full. I put in another card, but the same error. "card no. "1, or 2" full". I reformatted both the sandisk 16g cards, but it isn't happy. Won't recognize these cards being formatted, which I did in camera. Everything else seems fine. At the time of the error, there was only one card in camera. It actually took one shot, after formatting cards. I'm not sure what to try
