325185 Zen Cart Fix

We have Zen Cart up and running. We use Easy Populate to load vendor files to our cart. Some of our vendors want customers to be directed to their website instead of to our shopping cart. I was told to use the product type- document-product or document-general so that the "add to cart" button would not show. I uploaded 1 item through easy populate and it screwed up my whole database. Although my admin looks fine on the site it now says that all items are both categories/products and documents. None of my items display although all the categories do. My site is [login to view URL] Does anyone know how to fix this problem easily?
