Apple's iWork suite consisting of Pages, Keynote, and Numbers can store your documents up in iCloud and push them back down again to all your devices, iPhone, iPad, and Mac. However, sometimes when you try to open those files again, you get the dreaded "The operation couldn't be completed [LibrarianErrorDomain error 1 - Unable to initiate item download.)" or similar error. What it means is that the iCloud file has gotten lost in limbo. Luckily, what it doesn't mean is that your iWork file is lost forever. There's an easy fix!
