EDIT:
I’m getting two different codes when I view the source so the following may not be correct. However, at the very least you should fix the errors in the page.

That may be the source of your (and my) problem
Original Post:
This is the code you have for your link:
<td https://www.aweber.com/?212171="" width="70%">
<img src="https://www.aweber.com/banners/010222/ani-increase-sales.gif?id=212171" alt="Unlimited
Autoresponders by AWeber" align="bottom" border="1" height="60" hspace="5" vspace="5" width="468">
</td>
It should be:
<td>
<img src=”https://www.aweber.com/banners/010222/ani-increase-sales.gif?id=212171″ alt=”Unlimited
Autoresponders by AWeber” align=”bottom” border=”1″ height=”60″ hspace=”5″ vspace=”5″ width=”468″>
</td>
Somehow you combined your td and a tags.
