itunes purchase not fully downloaded
I have recently purchased the new spooky mens chorale abum welcome to the second half from itunes.
Although on the face of it it appears to have successfully downloaded, four of the twelve tracks do not play.
The message displayed says my computer is not authorised to play the track. When i try to reauthorise it following the prompt it says the computer is already authorised.
The remaining eight tracks play perfectly.
I have only had a similar problem once previously when I purchased the Answer's album Solas.
This album simply would not play and I have never had this problem resolved.
Any suggestions please
