OSC / CRELOADED PHP Bug - SEO URLS

My site [login to view URL] has Ultimate SEO URLS installed, with some custom modifications made. Everything is working correctly, with urls showing all required information. However, since installing this contribution, every product page has completely disappeared from search engines. When google tries to crawl the site, I receive an error for every product page that exists, with an error message saying that the page can not be found. THIS IS NOT AN SEO ISSUE. This is a problem with either [login to view URL] or one of the files associated with the SEO URL's contrib. I need this fixed urgently.
