Problem downloading with itunes

I recently purchased the "Awakening" score from itunes. It downloaded all the tracks but it keeps stacking when downloading the booklet score showing a message saying unable to download the booklet because of no internet connection or i dont have the right to download the booklet.

Anyway, I really dont care for the stupid booklet but everytime i open itunes it starts downloading it and just before the end the same message appears again and again. It happens even when i quit itunes. Itunes reopens by itself and its starting to download again the booklet (unsuccesfully of course)

Any suggestions for stopping doing this?
