Metastock Location Inventory

Just downloaded the app using the free trial. I began to use the tutorial video to install the app, you are supposed to enable 2 Metastock apps on your theme. My theme only showed the one app. When I contacted support asking for guidance, they responded that they "didn't have time to build customization on the app" and they suggested I "uninstall the app before I got charged". Not sure how I was needing customization, I just don't think they wanted to assist me.
