License on server with no internet access

Hi guys,

I have a production server (A) which has no internet access. I deployed the application on IIS and ran it there (localhost) without a key in Web.config. It did not complain.
Then I tried to access the application from a computer on the LAN and got the attached popup about Licensing.
So, I “purchased” a Community Server license (0.00 USD) and copied the key in the web.config of server A. However, this did not change much, since the server  has no access to the internet and the license could not be activated.
So, I copied the key to an application running on another server (B) with internet access, removed the wisej-server.lic file which was there from another license activation, statrted the application and had a new wisej-server.lic generated.
Then copied this wisej-server.lic from server B to the server A. But I still keep seeing  the license popups.

What am I doing wrong? Do I need to de-activate the license from B? How do I do that? In my Wisej account page, when I click on Manage Activations it takes me to editing my profile.

Or is it something different?

Best regards,
Alex
