Hi. Don't know if anyone can help, have tried searching the net to no avail. We have a WACS7000 and I can't play any of my MP3 downloads that I purchased from AMazon on it. They play on Windo0ws Media player or any other mp3 device but although they copy, when I go to actually play them on the WACS, they just skip through one after another and "fail to play". Any suggestions gratefully recd.
