System Error

First, make sure your browser is not working offline.  To do this, open a web browser window and click on the File menu.  There is an option called "Work Offline" - make sure it is unchecked.

Second, try going to the Settings panel on the player and changing the media server protocol setting.  (If it is set to "http" in the drop-down menu, try "mms/rtsp" and vice-versa.  NOTE:  only "mms/rtsp" works on Mac OS.)

Finally, be sure to allow the player through any firewalls that might be blocking the content.  For more firewall information from Microsoft, visit:
