Hi Ken I've tried playing the shows again after removing the music files and they worked fine, playing all the way through. I then added the tracks back and the same problem occurs, they just stop, close and go back to my desktop. Thank you very much for the PDF document, that's very useful. I am struggling to see if there is an answer or solution for this problem though in there, I don't seem to be able to find one. Was there a specific page you had in mind? Thanks Amanda
