Playback not working on BB Manager

Has anyone else had trouble with the Playback not working on BB Manager? I downloaded BB Manager a couple of days ago and cannot get any response from the Playback function. the Play and stop buttons are grey with muted grey lettering on them and the BPM slide has a round button which doesn’t move.

Do you have a project open in your BeatBuddy Manager? And is a song selected?

Thanks for your reply. I think I’m sorted now and have it running. I just have to learn how to use it:-)
