I've just tried to open a couple of old Pages and Numbers documents and have been met with the error "This document is too old and cannot be opened. To open it, save it with Pages '09 first." But I don't have Pages '09. Apple deleted it when I upgraded - I've got Pages 5.5 and Numbers 3.5. So it seems all my old documents are lost. I can understand an old program not being able to open a newer document, but the other way around? Why? Why can't the new version of Pages/Numbers read all older formats? It's like Photos. Why did downloading Photos cause iPhoto to disappear?
