Ultra Memory card suddenly stopped being detected. What to do?


I have a Sandisk Ultra Class 10 16 GB memory card. It is about 8 months old. I have been using it alot and suddenly today when I removed it from the camera to transfer the files to the computer, it couldn’t be detected. Even if I put it back in the camera, the camera would no longer detect it. It just doesn’t show any response to inserting this memory card. 
I tried to check the card port with another similar memory card. Both the ports detect that card but they won’t detect this card.

Please tell me what can be done to get it working? If it is dead, is there any way I can get the files out at a service center or something similar?

Thanks for the help!!
