some items were not copied to iphone
I plugged in an ipod recently and since then, I am unable to sync all the items from my iTunes to my iPhone, error message appeared saying"some of the items in the iTunes library were not copied to the iPhone, because you are not authorised for them on this computer" but the computer is authorised and have repeatedly authorised it again and again but still unable to sync some items, any idea how to resolve this.
iPhone 4S, iOS 6.1.3
