Ddj 1000 not controlling rekordbox windows 10

Ok guys I'm new to the DJ industry. I just purchased a Ddj1000, downloaded rekordbox and the Ddj 1000 firmware. I synced my Beatsource account to rekordbox. When I upload a track on rekordbox to the " deck" section I can only play and pause the track with my controller. THATS IT. It doesnt let me do anything else and theres no sound. HOWEVER, if I " preview" the song on rekordbox itself there is sound but I cant control it at all with the controller, not even play or pause it. HELPPP
