Ads dont work in my VB

[jan1024188]

Ok, so I went to edit template for default style, and this is my ad_showthread_firstpost:

<li class="postbitlegacy postbitim postcontainer">
<div class="postdetails" style="text-align: center;">
<vb:literal>
<OBJECT CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" WIDTH="728" HEIGHT="90" CODEBASE="http://active.macromedia.com/flash5/cabs/swflash.cab#version=5,0,0,0">
<PARAM NAME="MOVIE" VALUE="http://img.servint.net/yearafteryear-728x90.swf?clickTAG=http://www.servint.net/index.php?refid=AFE802379527">
<PARAM NAME="PLAY" VALUE="true">
<PARAM NAME="LOOP" VALUE="true">
<PARAM NAME="QUALITY" VALUE="high">
<PARAM NAME="SCALE" value="noborder">
<EMBED SRC="http://img.servint.net/yearafteryear-728x90.swf?clickTAG=http://www.servint.net/index.php?refid=AFE802379527" WIDTH="728" HEIGHT="90" PLAY="true" LOOP="true" QUALITY="high" SCALE="noborder" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></EMBED>
</OBJECT></center>
</vb:literal>
</div>
</li>

It used to work, but now after 2 upgrades of versions (I have 4.1.7 now) it doesnt work anymore.
Also if I make any ad via Advertising in admin panel, nothing shows up either. I feel like this is some sort of template problem...
