iTunes 11 download iTunes Extras keep getting Error-19
I've downloaded Avengers with iTunes Extras using iTunes 11 running under OS 10.6.8. Film downloads fine. Everytime I try to download extras it gets to the end of 1.65gb then comes up with (err = -19). It lists the file in iTunes but it is greyed out. When i click on it, then go to 'get info' it only says 45.5mb but it says it's location is iCloud. Surely it should have downloaded into my iTunes media folder on my iMacs hard drive. Been in contact with Apple they don't seem to know how to solve the problem. Directed me to a discussion on iTunes LP's which is from 2009.

They also keep going on about firewall and web acceleration. It can't be a firewall issue i've been downloading music and films the past couple of days and I don't use any web acceleration, plus I have set up rules in my firewall preferences to allow the iTunes url's access. Anyone have a clue as to what is happening, personally I think it's a store and iTunes 11 problem.
iMac, Mac OS X (10.6.8)
