I am a permanent licenser who wants to activate a new license in order to continue translation work. When I try to click an activation button, the process circles goes around without any stop.
Then I found an error message saying "We cannot connect with an activation server. Please confirm your activation server address via a provider."

I am still a beginner who can't understand how Trados works out who needs a translation assignment. 
Please help me solve this problem so that I can use a new Trados.

My name is Motoko Naito with Trados Studio 2021.
