Authorizing the use of purchased iTunes Store music
On a new PC laptop and wanting to play purchased music. Laptop device has been authorized. Click on song and a authorizing window opens stating the computer is not authorized to play this music. Window requests Apple ID and password. Apple ID box is preloaded with ID which is not the current iTunes account ID but, is my Support Community ID. Change ID to authorized ID and use associated password and reauthorize. New window states incorrect Account. Where is this new ID coming from and how do I fix this?
