It is likely that your firewall is blocking your access to the webcast stream.

If you are attempting to view a LIVE webcast at its scheduled time:

• Open a new Internet Explorer Window
• Copy the link below and Paste it into your Explorer’s address bar:
  mms://a595.l3762354594.c37623.g.lm.akamaistream.net/D/595/37623/v0001/reflector:54594

If Media Player does not automatically open, or you see a security message within Internet Explorer, you are being blocked from accessing this video stream. This is most likely caused by your company or personal firewall. Forward the link above to your IT department to make the necessary changes to your firewall.
