  1. Review the Hardware and Software Requirements page to ensure that your computer has the necessary hardware, software and Internet connectivity to view the webcasts.

  2. Do you have Adobe Flash Player 10 installed on your computer?  Check Adobe Flash Version If you do not have Flash Player 10, Update Adobe Flash Player

  3. Do you have sufficient bandwidth on your Internet connection to view the webcasts?  Note that a broadband Internet connection of 300kpbs is required to view the video webcasts.

To change the transfer protocol to HTTP follow these steps: Start => All Programs => Accessories => Entertainment => Select Windows Media Player. In Windows Media Player: Select the "Tools" menu => "Options" => Select the "Network" tab. Deselect Multicast, UDP, TCP. Leave HTTP selected. Select OK and close Windows Media Player. NOTE: In order to receive webcasts using these deselected protocols you will have to reselect them. The steps to change the delivery protocol may vary based on the version of the Windows Media Player and version of your Windows operating system.

    5. Still Having Trouble?
      If you still cannot play the webcast after these steps, please contact your system administrator for further troubleshooting support.
