Yes I turned it on and off yesterday and disconnected from the power overnight. But it's the same now.

Loading... then stopped and then the field is clear. After 1-3 seconds the MC200 returns with the default settings (volume on 65) all my titles are in queuing and stopped. If I click the play button its always the same.

Is there a way to reset to factory settings or to an older firmware?
