I just installed Google Base Feeder and I still get an error on google product categories. Can someone help me to adjust the problem? I don't know where to go to submite product categories for google base. I won't be able to change my site's product category the way google requires. I just need to add google product categories extra besides my product categories. It also geve me error on mpn. I don't have mpn information for my products. I just left blank. I have Zen Cart 1.3.8a and I installed right one for that edition.

Thanks
