IE errors

IE errors

Hi all.

I using on site http://kulbet.katowice.pl script who require jquery.
I include latest version of framework on my server and include in to head section code
  1. <script type='text/javascript' src='js/jquery-1.4.2.min.js'></script>
In Chrome, Firefox and Opera site look good. All slideshows are displaying.
Unfortunately in IE (8 and below) are displayed critical errors in jquery script file.
Page  http://jquery.com/ is displayed great without any errors, so I include to my page script directly from their source:  http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js
Errors was displayed too.
I don't know what's happens. Can you help me?
I had read many topics from google, but no one had that problem.

I attach 4 screenshots with error alerts generated by IETester app and clear IE 8

Detail of error in IE:
