My Sansa Sport freezes

My new Sport sometimes freezes on pause. It’s very hard to get it going again (turning it off doesn’t work. It just returns to the freeze state). I press stuff randomly and somehow it restarts. Any help out there? Thanks, Anne

what type of file are you listening to and how large is the file? audiobooks that are in one large file can take up to a min or so to start playing again once paused some other users ahve reported.
