I am not familiar with that brand of camera, but here are a few suggestions, some of which you may have tried: 1)Make sure the SD card slide is not in the lock position. I had a card where the slide became worn from use and every time I either put it in my computer or camera it would slide to the lock position. 2)Make sure your card is compatible with the camera (not too large of a GB size). 3)Format the card in your computer first. Some cards if viewed in a Digital Camera will not work due to a file change etc. 4)Try a different brand of card. 5)Check your batteries with a digital meter. Any battery that drops to 1.0 to 1.2 volt and the camera will not function properly or not at all. New batteries fresh out of the package may have a faulty one.
If none of this helps, check and see if there is a software up date. Best of luck.
