Problem with SMF, phpadsnews and adsense for search

[winnet]

I integrated phpadsnews with smf working great, no problem with all banners, display correct, redirect working well, all OK.
The problem cames when I insert a google adsense for search banner;
the banner (the search box and logo) is displaying OK, but when I put some text and click on search button an error message came, something with session verifications failed or something like this.
anyone came give a little help? I'd like make this working.

This is not an answer to your problem, but a question.

How did you put the google stuff into your phpadsnew, and how did you get it to work on your SMF site?
I added the google code as text banners, and in phpadsnew they appear. BUT, when I put the HTML code into my SMF site, the google banners doesn't show up. IF, however, I use "interstitial or floating HTML" the google ads appear, but then it's a floating HTML block, which I don't like. I currently use the "Remote Invocation" which gives me normal HTML code to use on my site, http://forum.softdux.com
