Problems playing a song downloaded from Itunes
I have downloaded numerous songs from Itunes without problems. I downloaded a song yesterday, paid for it, received the invoice; when I try to play it, a messages tells me "the device is not authorised to play the song"".
I get the option to authorise the device which I follow. A message then tells me the device had been authorised before and that it has been authorised again.
I again try to play the song and the same message "device not authorised....". I authorised the device over and over to but it will not work.
Any hints as to how to remedy this problem?
Windows, Windows 6
