Go to your sql databse and to the [prefix]_ads section and manually add the html.

The ad code input replaces html tags with browser friendly character entities.


Example:

This:
<a href='#'><img src='lol.png'/></a>

Is changed into this:
&lt;a href='#'&gt;&lt;img src='lol.png'/&gt;&lt;/a&gt;


Just go to the database and add the html manually into the "text" field.
Had that problem awhile ago.
