iTunes purchase not able to access or play
I purchased an album using the "complete the album" option. The album is Pulse by Pink Floyd. I had previously purchased one song. After purchasing the rest of the album several songs will not play. I'm told the computer is not authorized to play the selection. This is the same computer I used to purchase the album. I enter my user name and password to authorize the computer and get a message stating that this computer is already authorized. Need some help please.
Windows, Windows 10
