Bug? While Installing

I'm not sure this is a bug, but thought it might be.

My Purpose: I wanted to create a book page with several child pages that I could use as a template for cloning additional book page sets.

This is what I did:
I had just installed the node_template-5.x-1.6.tar.gz module onto my test website. After configuring it, I created a book page, and then created 3 child pages. When I pressed the "Set Template" tab at the top of the book page, this error message came up.

user warning: Unknown column 'shared' in 'field list'
query: INSERT INTO node_template (nid, is_template, shared) VALUES
(229, 1, 0) in
/home/winterss/public_html/winsewtest/includes/database.mysql.inc on
line 167. 

Then, when I clicked on the "My Node Templates" Menu on the left side, it brought up the "Node Template" page with this message:

user warning: Unknown column 's.shared' in 'field list' query: SELECT n.nid, n.uid, n.type, 0 AS cid, 1 AS node, n.title, n.status, n.changed, s.shared FROM node n INNER JOIN node_template s ON n.nid = s.nid WHERE s.is_template = 1 ORDER BY changed DESC LIMIT 0, 50 in /home/winterss/public_html/winsewtest/includes/database.mysql.inc on line 167.
You have no node template yet.

What is the matter? And How Do I accomplish this?
Best Wishes,
