TOPIC: Problem during license switching

I get "you can deactivate and activate again only one time" error message when switching a license between computers.
I'm currently switching server and checking the run difference, but when i want to return the license to the first computer after i put it in the second computer i got this error message and now i cannot use the license on either computer.
how to resolve this?
thank you in advance
