Video not showing after taking

I took a real cool video of my grand kids singing in to the fan. After, I downloaded to Facebook. The video worked just fine. well, I go to work this morning and wanted to show it to a few guys. I navigated to 100MEDIA to show the video. All it was just sound, no video. Anyone have a idea if what happen and how to fix it??

Update: I can play the video on the phone but can not on the computer. the other mp4's play's fine on my computer

The file format is 3GP, and you need to convert it to something your computer can play. There are a bunch of converters you can download.

Under stand that. But like I said before, 3 other mp4's play without a problem on my computer, There seams to be no difference from the one's that don't work to the ones that do work.
