Help Bridge locked all my files

I am new to Bridge. I downloaded it today and open a raw file from my camera sd card. I played with the photo in camera raw and then closed it. Once I did that, I can no longer see any pictures on my sd card. They appear to be all gone. I tried putting the sd card back in my camera and there are still not any pictures there. HELP! How do I get my pictures back? This is all that is showing on my card now.en I try to access the card from Bridge it just show a pad lock
