As far as I know, there aren't any DR5 files available for download (though the ability to do so is there). There might be one for "Lord of the Flies". That's a good idea - I'll add it to the list! EDIT: Just realized who this is - hello there!
On many of the newer analysis files you can download the PDFs of the Story Engine Settings report, but I don't think there are any DR5 files to download. Also note that if there were any they would only work with the latest Mac version of Dramatica (Dramatica Story Expert), so I'm not sure if it would help you anyways. You can always go in and choose the eight dynamic questions and Domain, Concern, Issue and Problem of the Overall Story Throughline for the story you want and save it yourself to the Examples folder.
And then send it to me so i can upload for everyone to have!
