Yes, I built the one on www.triassicgames.com (which is one of my sites).
Do you get this error every time for all broadcast apps or just for one?
Have you tried shutting down the Player on your Android device and restarting?
To make sure that it is really shut down (the close button sometimes doesn't really close everything) you go to Settings->Application Manager and find v1076 Player in the list. Then click on it and click on the 'Force Stop' button to make sure that it really has stopped.
I just used the close button the Player on my device and went into the Application Manager and it indicates that the Player is actually still running. (The 'Force Stop' button was enabled.)
