Why was I able to see the test but have issues with the actual webcast?

The actual webcast will be streamed at the same rate of the test, 256 Kbps. If you were able to see the test but are having trouble viewing the actual webcast, it means that there is something taking up too much bandwidth on your network. Do what you can to reduce any other heavy bandwidth use on your computer and contact the Administrator of your network for additional help.
