In some cases, especially if you have a very low bandwidth network connection, it will take some time for a video to buffer and play. 

First, please click on the "If the video is not loading, click here" link. The system will automatically check to ensure that there are no problems with the video on the server. 

If the video is OK and you still can't see it, either switch to a faster network connection or refresh your browser. 

Thank you.
