Installed DeskScapes, Placed Planktonic 2 at the location by the other dreams. Nothing,

If you do, for the new Plantonic 2, do any of these - if changed to - have it play:

If you go to:
C:\ProgramData\Stardock\DeskScapes\ExtractedData
And into the newly created 'Planktonic 2' folder, and try to open the video, does it play and what video player opens to play it?
If you right-click the video file, properties, what is the file type?
