My b2evolution Version: Not Entered

I recently changed my archive to be an alphabetical list, and now when I go to view it I get an error displayed, as well as a javascript error showing in firebug. I haven't used the archive before so I don't know if it was present before upgrading to 4.0.3, or before chaning it to alphabetical.

My blog address is http://www.rhinomangraphics.com/lightscribe

The error message displayed on the archibe page itself is:

Fatal error: Class 'ItemListLight' not found in /home2/webjdcne/public_html/rhinomangraphics/lightscribe/plugins/_archives.plugin.php on line 476

Firebug also shows 1 error
ThumbshotPopups is not defined
http://www.rhinomangraphics.com/lightscribe/?disp=arcdir
Line 36
If I click into that error, line 36 looks like:

ThumbshotPopups("thumbshot", ThumbsLinks); 

In perspective that section looks like:

<!-- headlines: -->
30 <script type="text/javascript" src="http://rhinomangraphics.webjdc.net/lightscribe//rsc/js/jquery.min.js?v=4.0.3"></script>
31 <script type="text/javascript">
32 /* <![CDATA[ */
33 jQuery(document).ready(function() {
34 if( ThumbsLinks = jQuery(".bText a[href^='http:']").not("[href*='" + window.location.host + "']") )
35 {
36 ThumbshotPopups("thumbshot", ThumbsLinks);
37 }
38 })
39 /* ]]> */
40 </script> 

Any help would be greatly appreciated.
