Machine specific Xopus license

In the Xopus folder structure, you will find '\license'. New installations come with 'localhost.txt' and '' for dev use.

To host from a web server, this folder needs to contain a license that is specific to the host machine's name/ip.  

We've been running Xopus for several years on a machine that we are now ready to retire. I need a new machine specific license file for the new machine so that Xopus doesn't complain. Yes, our corporate use license is up to date, but I need a 'machine license'. 

How can I get a new machine specific license crafted or issued? If I remember right there used to be a way to form it through the Xopus support page, but I sure can't find this option. How is this done today?
