oh man.... i said 'thanks' to fast. You just change version number inside xml file, right?

If not then instruction is wrong. in 3.5 there is no 'headerinclude' template - there is a 'header' tempalte. And 'header' templaate doesn't contains:

Find:

<script type="text/javascript">
<!--
var SESSIONURL = "$session[sessionurl_js]";
var IMGDIR_MISC = "$stylevar[imgdir_misc]";
var vb_disable_ajax = parseInt("$vboptions[disable_ajax]", 10);

so is bit hard to edit enything... ;]

I haven't check rest of instruction but I assume is very similar to this....
