Convert old OS X Keynote format

I have a Keynote file created on an older version of Keynote which I'm now unable to open using the newer Keynote version (6.2). The message I get (loosely translated from Norwegian) is "The presentation can not be opened because it's too old. To open it you first need to save it as Keynote '09". So what I need is someone with an older Keynote version (5.x I believe) to open the file, save it as Keynote '09, and send it to me.
