When I try to validate, it's saying I don't have ads on a page that in essence not on my site anymore. I use mod_rewrite, and change the output URL, but for some reason, the validation process is still finding the old url. Will this eventually come out of it? I finally got the ads on 29,000+ pages, and can't even get 'em to count. **SOLVED**
The validation is based on what Google knows about. So once it drops out of Google, it should be fine.
