Having Problem with Adsense Deluxe Plug-In

I have the 2.1 Version, I had Adsense Deluxe Plug-In Installed, Does that mean you can only have 3 Adsense Ads at a time, I want to edit with HTML, But now since I have this Plug-In, I do not have anyway to edit this page. Could someone give some assistance with this, I have been posting a bunch of questions on this forum, No Replies, What is the deal?
