Help Video Transfer/Play Issue


So, I had to transfer all my videos and pictures to my computer b/c of the gallery error that everyone is having. I then formatted my SD card... so all my pics and videos were erased off of it.

I try to play the videos on my computer...... and NOTHING. Just a still picture. It doesnt even have the video as a video file.. just a jpg file

Any help?? Suggestions. SUPER upset over this as I have TONS of videos of my son that wont work
