I implemented the mod but I must have missed a step. I updated my .htaccess file in the store root with the data from the one in your zip. I made the changes noted to config.php, auth.php, smarty.php, and froogle.php. I uploaded the included files into /include... and /catalog.
But I'm still geting:

What did I miss?
