How to save a too old keynote file in '09 version?
I want to open an old keynote presentation in Keynote '09, but program responds that file is too old, and advises me to save it in '09 version. But how to save it when I can't open it? The file is from 2011 and it must have been produced in '07 or '08 versions...
