Help restoring pictures from a SD card


I need your help. I have a Nikon camera with a SanDisk Extreme 16GB SD card in it.

I was on a trip taking pictures when suddenly an unexpected error occured. The camera’s screen displayed a message saying “the card may be damaged. Please change the card” or something like that.

Now, I really need the pictures from the card. I was told to try to recover them with Recuva or other similar programs, the problem is that neither the camera nor the PC can read it. I even tried putting it in another camera and another PC but nothing happened.

Is there anything I can do to recover the pictures? Thanks in advance.
