Keynote 6.2.2 will not open a keynote file created in 6.2.2
I was sent a keynote file by a work colleague and we both have Keynote 6.2.2 on our MacBook Pro's. My MacBook will not open the file sent by my colleague even though it was created in version 6.2.2 I get an error message saying I need to download the latest version from the App store. Even after trying for a later version the App store says I already have the latest version installed... any advice please?
Powerbook 15", Mac OS X (10.4.6)
