Sounds like you didn't set up your SQL File correctly. Go to MYSQL and search for google_ and delete all references to google_base and google_froogle, etc... then resubmit your googlefroogle.sql for query.

One way to tell if you did it wrong, when you go to the Google Base Feeder Configuration in admin, if you only see ftp username / password and server. You did it wrong.

You should see like 25 configuration lines you can change.
