"Stock by Attributes" problem

I have installed stock by attributes as the instructions said. and it seems that all the files went on the server correctly. it's supposed to make something to click on at click on Catalog->Products with Attributes Stock but that is not showing up under catalog. anyone know what the problem might be?

I am using Zen Cart v1.3.9h

Thanks to anyone for any help

Did you run the SQL patch ?

I did. I thought maybe it didn't work so I tried it again and it says it's already installed. but it's still not showing up

Do you already have attributes set up and assigned to any products?

What is the url for the site?

the site is https://www.allgengames.com I don't have it assigned cause i can't find the link. I was able to find the table in phpmyadmin section of my cpanel but it's not showing up anywhere in my admin section of zen cart

sorry charmedbytina2 I misread your question the first time. I do have a couple of attributes sat up and one is assigned to the only product on the site right now. I haven't been setting up the site any further because this addon would make everything alot easier if working properly so I've been holding off til i can figure it out.
