Demo Server Configured Correctly?

I really enjoyed how easy it was to setup a show, but when the show plays the on air button is not lit up, even though it indicates that a track is playing, and I don't hear anything when listening to the live stream at http://airtime-demo.sourcefabric.org:8000/airtime.ogg

The show was scheduled today at 12:55 EDT. I've read other docs saying to check the logs, etc, so I was wondering if you could please advise.

Thank you.
