Xdj-rx

Hi everyone, I bought the xdjrx recently and have now got to grips with it and know what I'm doing. However, lastnight, all of a sudden my play/pause button on the left deck started doing this weird thing. And what it's doing is instead of just stopping instantly when I press it, the track when I press it, slowly comes to a stop. And same when I press play. Can anyone help??:)
