Goolge Base not accepting my URL

Google base isn't accepting my URL: http://www.domain.org/index.php?route=feed/google_base

It just says invalid URL and it won't take it. I've been to the URL myself and it shows the data just fine, but Google won't take it. Am I missing a step somewhere?

This installation, while configured, hasn't been modified and has only been installed for about a week.
