Itunes will not play a track I purchased
I purchased a track yesterday and it played on my computer fine. I have gone to it today and it says this computer is not authorised - I authorise it although it has already been authorised and says that I have now re-authorised this computer - then go to play it again and exactly the same thing happens. So I reauthorise it and off we go again, exactly same thing happens, it wont play and says computer is not authorised?!! Maddening!!!! I have no idea why.......I have authorised maximum 5 computers so I deauthorised them all and then just authorised this one.... that didnt work either. HELP
