Unable to download from Website

I am unable to download the specific items 3D Printing, Laser Engraving and Cutting, and CNC Carving from the bottom of this page: https://snapmaker.com/snapmaker-2/downloads

I get a message that says:

oops

You’re not authorized to access this page

Take me back to the home page

I can access the Luban manual (the first item in the set of User Manuals)

Based on the picture, it doesnt look like its the same content in the main manual.

Thanks
Mark
