Ads in Theme Panel for 3.1

So I’m still running the 3.1 version of the theme because I have a bunch of custom coding in td_module with the $buffy and I cannot figure it out in the new PHP codes.

I’m trying to use the theme panel’s ad area. I want to use the inline/bottom ads and I know its a fix in the next version after 3.1. Is there a specific file I can update so I don’t have to update the whole website?

Thanks in advance!
