Cerberus hangs in initialization of music-module

When I add the music-module to the designer, my cerberus hangs in the initialization:
music = new GTM.GHIElectronics.Music(5);

The music_finished was added to the programStarte():
music.musicFinished +=new GTM.Music.MusicFinishedPlayingEventHandler(music_musicFinished);

Is there anything I’ve forgotten?

Is this the ethernet or non-ethernet firmware?

We have some threads with info about it:


It’s the ethernet-Firmware.
Maybe it is the same issue, described in this thread: http://www.ghielectronics.com/community/forum/topic?id=11052
(thx to Architect for advice)
