Check accessibility / Highlight accessibility Issues

When I click the "Highlight accessibility Issues" link on a node that I am editing, I get the following error:

Fatal error: Call to a member function getReport() on a non-object in /public_html/sites/all/modules/accessible_content/quail/reporters/reporter.demo.php on line 43

The file is there and on line 43 is the following line of code:

$problems = $this->guideline->getReport();

Some times when I click on this feature, nothing will happen, even though there is an "Error Suggestion" (ie. Data tables should contain "th" elements) supposedly on the node page. I check my error code for any type of Javascript error and don't have any (doesn't look like Javascript is being called anyways when you click this link).

The version of Quail that I am running is: quail-lib-0.2.1
I'm also running FCKeditor v.6.x-1.4, not sure if FCKeditor is compatible with this feature.
I am running Drupal 6.15.
I am running Administrative Menu 6.x-3.0-alpha3

The "Check Accessibility" link right beside "Highlight accessibility Issues" also does nothing when I click it.

Maybe these issues are a lack of knowledge of this module, but I don't think I missed any steps in setting it up. When I'm viewing a page while logged in as admin, I see visible errors, but when I click the "Accessibility" tab, it also shows:

Severe Errors (0)
Moderate Errors (0)
Suggestions (0)

Let me know if you need any more details to help solve this issue.

Although I've never taken much interest in making sure my sites were fully accessible, I sure do appreciate the effort put into this module to date.
