First, version 3 behaves the same as version 2 when you go to Settings -> Queue and disable "Advanced Queue Mode".
Do I understand correctly that when you press play in version 2, playback starts (you see the play time advance) but you hear no sound? Have you enabled fade in oder delayed playback start?
Oh and version 2 and 3 are completely independent. If one behaves strange, deleting the other will not change anything.
