Do you have a personal firewall? Are you behind a firewall at an office?
Try viewing in another browser. Some of our customers have had problems with Internet Explorer and have been able to view in Firefox and/or Google Chrome.
Try clearing your browser’s cache. See http://www.wikihow.com/Clear-Your-Browser’s-Cache.

For example, if you’re trying to watch a video and download something at the same time, your video may slow down or even stop loading altogether. Also, if you’re on a computer network (even a home network) and someone else on the network is downloading or watching videos, it very well could affect your video download.
