Google changed the script location, this should fix it if you are getting the generic 'nothing I can do URL".

In Templates: Navbar after this

<div id="globalsearch" class="globalsearch">

Add the following (first replace the URL and Partner ID from adsense:

<form action="http://www.yourdomain.com/yourforumurl/google.php" id="cse-search-box">
    <input type="hidden" name="cx" value="partner-pub-xxxxxxxxxxxxxxxx:xxxxxxxxxx" />
    <input type="hidden" name="cof" value="FORID:9" />
    <input type="hidden" name="ie" value="ISO-8859-1" />
            <span class="textboxcontainer"><span><input type="text" value="" name="q" class="textbox" /></span></span>
            <span class="buttoncontainer"><span><input type="image" class="searchbutton" src="{vb:stylevar imgdir_button}/search.png" name="sa" onclick="document.getElementById('navbar_search').submit;" />  </span></span>
        </form>
<script type="text/javascript" src="http://www.google.com/coop/cse/brand?form=cse-search-box&amp;lang=en"></script>

If you dont see globalsearch it is because you have modified your Navbar template and need to revert it.
