Thank you!

There is a free trial version, but unfortunately this does not contain/play the
OP video. The full version is non-free (in all senses).

Is there anything I can do to help with this on my end?
Would the video file itself help? (Since the video is on YouTube as well, I
have no compunctions sharing the version that ships with the game in the
interests of interoperability.)
