Btw installed on 3.8 and so far so good. No real issues.
There is one edit though that should be changed

In step 2b you say paste this

STEP 2b - EDIT Template: FORUMHOME

FIND <!-- main --> 

FIRST - Copy all the code from <!-- main --> to <!-- /main --> (Including 2 main comments) and save it into you editor of choice as this will be used in an upcomming step.

Then Replace <!-- main --> ...code... <!-- /main --> with the code below

<!-- main -->
<!-- Tabbed Forum Home -->

<div id="ajaxTFH" class="TFHmenu2">
	<ul>
		<li class="selected"><a href="tabforumhome.php?tabcat[]=1" rel="ajaxTFHcontentarea">TAB 1 NAME</a></li>
		<li><a href="tabforumhome.php?tabcat[]=1&tabcat[]=2" rel="ajaxTFHcontentarea">TAB 2 NAME</a></li>
		<li><a href="tabforumhome.php?tabcat[]=1&tabcat[]=2&tabcat[]=3" rel="ajaxTFHcontentarea">TAB 3 NAME</a></li>
	</ul>
</div>

<br style="clear: left" />

<div class="TFHmenu2line"></div>

<div id="ajaxTFHcontentarea" style="border:0px solid gray; width:100%; height: 100%; background-color: white; padding: 0px"></div>

<script type="text/javascript">
	var mytabs=new ddajaxtabs("ajaxTFH", "ajaxTFHcontentarea")
		mytabs.setpersist(true)
		mytabs.setselectedClassTarget("link") 
		mytabs.init()
</script>

<!-- /Tabbed Forum Home  -->
<!-- /main -->

Now in any further releases i would just leave the background)color: white out of the div style. Since no one hardly uses vBulletins default colors

just saying
