I use version 3.6.2. Try this.

Find this line near the bottom of your postbit:

<!-- / post $post[postid] popup menu -->

After it, put in this code:

<if condition="$post[postcount] == 1">
<div style="padding:6px 0px 0px 0px">
<table class="tborder" cellspacing="1" border="0" width="100%" align="center">
<tr>
        <td style="padding:0px" align="center">
              Google Adsense Code here
        </td>
</tr>
</table>
</div>
</if>

Make sure you have another </if> after the above code to end your postbit (so there should be two total). This will put your Google Adsense after the first post of each thread. Works for me. Hope it does for you.
