Why is my URL not being recognized for an imported form?

I am trying to create a new form by importing the following form available here: http://www.aabb.org/membership/governance/committees/trpdocs/AABB%20Jan%2018%202017%20Board%20Assessment.docx However, I'm receiving an error message that the form is not found through the link. Can you please advise. Thanks. 

Unfortunately, we do not have an option to import forms from word files.

This is why the import tool does not recognize the URL.
