My SD card isn't working?

I bought a Nikon Coolpix (not sure the entire product name) and it was working fine for a while and then when I went to take a picture on it, the picture took, but it did not save. Then after that, the card wouldn't go into the slot in the camera anymore. Then after a few days it went back in, but now when I turn on the camera a screen comes up saying "This card cannot be used". I've tried multiple cards and it still isn't working.Is there anything I can do about this?
