Pages 5 destroys documents

I ust opened a 20 page storyboard created in the previous version of Pages. Pages 5 tells me it has "removed all objects from tables." Those objects were dozens of storyboard images! They are gone. Even though I did not save the document, aparently Pages 5 saved it for me and the previous document is unreoverable.

Of course I have most of those images saved elsewhere (not all, sometimes I will cut and paste a screen shot into a stoyboard) And it is possible to recreate the pice with several hours of work. But this is just infuriating and completly unacceptable.

This downgrading of program features with every new version is becomming a patern with Apple software. It's even worse when the new version can't support files created in previous versions. And it is just insane that the new program actually destroys files created in old versions.

Am I actually now going to have to start using Word?

And, how do I go about opening my old files for conversion without destroying them?
