This may already be in a earlier thread but I cant seem to find any answers to my problem! I have just downloaded some TV shows from itunes and when I go to play them it says "this song is not authorized to play on this computer" Then under that it says "you can open itunes to authorize this song" Hmmm well Im already in itunes! Then I click open itunes and i says "Waiting for itunes to authorize this computer to play MYFILE.m4v" I have successfully authorized my computer numerously and it is currently authorized! So why cant I play the file??? Ive tryed De-authorizing then Re-authorizing, restarting itunes, restarting the computer and still it does the same thing. This is so dam annoying I have $100 worth of tv shows I cant play! And Apple support are taking a long time to get back to me! This is my last option, please help someone!
