3D FlipBook - Pro version install issue

I know this is not a new question... I have read many of the others with the same or similar title, and the response(s). I understand I'm to look in the "dist" folder for the plugin, but there is no "dist" folder in the downloaded zip. I have deactivated and deleted the lite version, unzipped all zipped files and looked through all of the folders. Installing the "3d-flip-book.zip" only gives me the lite version. My apologies if I've overlooked something, but I appreciate your help and response.

I purchased the Pro version earlier today.

Thank you.
