Hello, I am trying to edit a Keynote presentation (made on a previous computer) on my new rMBP 15" 2014 model. When I tried to open it using the pre-installed Keynote, I got a message saying that it requires Keynote 09. I copied the folder "iWork '09" from a backup drive and double clicked on it. I got an error saying that it does not work on my current OS 10.9.5 and require a reinstallation. I don't have the installation disc anymore. What suggestions do you have?
