David, are you getting any kind of error message? I had no problems opening either document with the same setup you have. I even re-downloaded the files to double check.
You are most welcome. I look forward to seeing what you create with Ren'Py. I'm sure it'll be much better than my own, not shared with the internet at large (for good reason), "Badly Drawn Stick Man's IA/UX Adventures." ;-)
