Airtime is offline, but ...

hi friends,
please help me with my problem:
on my machine running "Airtime" but indicator "ON AIR" is still no light, and stream is no available (message info - offline).
There is some screenshots:
2012-03-28 15.22-002.png = as you can see, some show is currently playing, but "ON AIR" is not light
2012-03-28 15.22-003.png = all services are right and are running (correctly)
2012-03-28 15.22-004.png = Icecast status talks that "Airtime" is offline
2012-03-28 15.22-005.png = from local machine I try connect stream on that server
2012-03-28 15.22-006.png = Airtime is offline, the same status

Please how can I run "Airtime" (let "ON AIR" is lighting)?

thanks for all
