I think 3.6.0 uses new table code. This is what I'm using now that works well for me (I also only show ads to guests):

PHP Code:

<if condition="!$GLOBALS['FIRSTPOSTID'] && $show['guest']"> <!-- GOOGLE AD -->

<br>
<table id="post$post[postid]" class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="100%" align="center">
<tr>
    <td class="thead" style="font-weight:normal; border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]" colspan="2">        
        Sponsored Links (Please login to hide these :)
    </td>
</tr>
<tr>
    <td class="alt2" style="border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]; border-top: 0px">
    <center><script type="text/javascript"><!--
google_ad_client = "INSERT YOUR AD CLIENT HERE";
google_alternate_ad_url = "INSERT YOUR AD URL HERE";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text_image";
google_ad_channel ="";
google_color_border = "333333";
google_color_bg = "444444";
google_color_link = "FFFFFF";
google_color_url = "BBBBBB";
google_color_text = "AAAAAA";
//--></script>
<script type="text/javascript"
  src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script></center>
    </td>
</tr>
</table>
