Terrible Module...
Stay away from this module...
After adding a server it will start showing out of stock within a few days and you will constantly have to add new servers its just a headache.
Also I tried contacting support not only did they somehow lose my account they also have still not provided a solution to the issue 2 weeks later.

I am terribly sorry about the bad experience. If you still would like help our DevOps team can help you. We have updated the module to fix this issue. It now automatically imports all products and updates them. If they go out of stock it automatically hides them. This is controlled by a cronjob. It is a much better admin experience now.
