track not authorized to play

I recently downloaded an album from iTunes, and one track will not play because it says the computer I'm using is not authorized to play it. I am then prompted with a screen to authorize my computer. After confirming I want to do this, I get a screen saying this computer is one of three already authorized. After attempting to play the track a second time, I am prompted with the same message saying this computer is not authorized to play it. Unfortunately, my iPod is broken and not with me, so I can't troubleshoot it that way, if it would make a difference.

Thanks for any help, everyone.
