San Disk

I have a SanDisk SD card that while i was manually going into its folder i started copying images and movies to the desktop. The process was about half way through when all of a sudden it just froze. I tried restarting the process again and it froze again. After that i restarted the computer and the computer couldn't read the card. Trying the same card in the camera resulted in the same thing.

Are all my pictures lost or is there a way i can still get them off?
