Zeus...sorry to hear that
So it looks like you are stuck with the html catalog then. You mentioned above, that your catalog is in the catalog/ directory. By 'root' I mean that you need to generate the catalog in the root of the site, meaning where your cart.php, product.php, etc files are. I DO NOT recommend php file names, as there is absolutely no optimization to them, and it will hurt you. You simply need to generate the html catalog in the root directory daily and set your directory index to index.html.
