Importing AE CC project into AE CS6

I've downloaded a few AE projects I want to work with that were created with After Effects CC. My version of After Effects is CS6, so of course I am prompted with an error message if I try to import the CC files. I could contact the authors and ask if they would export that project as CS6 compatible files, but three messages so far have gone unanswered!

Is there a workaround or script I can use that will convert CC project files so that I can import them into CS6?
