I have just tried to download the Garage Band in app purchase for the RED loop pack for AIDS and it will not work. I get through the <purchase>, putting in my user ID and password and <buy> pages but after that it saysoperation could not be completed.'. I'm using an iPhone 6 with IOS 8.1 and on a very fast eduroam wireless connection at my university. What do you think is the problem? Is anyone else having this problem?
