Your contact page basically said to post this here so here goes.
Inside Virtualmin Pro I am seeing the message:
Now re-checking your Virtualmin licence …
… a problem was detected : Your serial number is licenced for only 1 servers, but is being used on 3.
What is going on is that I had an OS problem with a server on which I was running Virtualmin Pro. I had the OS re-installed. I re-installed VirtualMin Pro. I still had some problems. So I shut off Webmin & Usermin on that server, bought a server from a differnent company, installed VirtualMin Pro. And now I have deleted Virtualmin Pro from the old server (uninstall script), and I shut the server down. Now VirtualMin Pro is only running on my one server. But I still see the message. It’s like you have a counter being ticked that never decriments.
I don’t mind the warning, after all, it’s just an informational warning, but when will it go away?
