Video is not working on portable prezi

I prepared a presentation and embedded videos and make paths for these videos. When I use online presentation, there is no problem. But after I downloaded the presentation as a portable prezi, while I am using it, the auido of the video is working but video is not. There is voice but the screen is just black. I tried this presentation in other computer, it is working. Please help me to solve this issue. Thanks.
