Forum wont start. Help :-)

I have problem with one of my boonex instalations. Orca wont start. I'v installed three other versions and still something is wrong.

boonex/orca/ looks in FF3 so:

?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="http://78.133.178.111/boonex2/orca/layout/uni/xsl/home_main.xsl"?><root>
<disable_boonex_footers>0</disable_boonex_footers><header><![CDATA[
<div id="FloatDesc" style="position:absolute;display:none;z-index:100;"></div>

<div id="login_div" class="login_ajax" onclick="var t = ( event.target || event.srcElement ); if ( t == this ) $('#login_div').hide();"></div>

<div class="main" style="width: 960px">

and then some other stuff like that. In IE nothing happen.

Pls. take a look:

(Yes  - we have Smart Pro licence,

No - it;s not a translattion problem - after installation in english it's same)
