Nodeaccess not doing anything

Just installed this on a 5.2 drupal site. Some problems with the documentation led me down a wrong path, but it was minor:

Once you check the enable box and submit the page, no nodes will be accessible to anyone
other than the admin user. You just set permissions on the nodeaccess settings page
(admin/settings/nodeaccess) to enable access to your site.

It's actually in admin/user/nodeaccess, not admin/settings.

I enabled the module, and found the settings page, and checked the checkbox "Give node grants priority", since I'm using TAC lite as well.

None of the sections of the nodeaccess settinfgs page have anything in them. They're not clickable, expandable sections as one normally sees.

Turns out I had to run the update.php script and force the 1 update to run, even though I then received errors that the table already existed...
