Impossible to reset my license

Hi,

My computer is in repair, so I need to use my License on an old one, and I cannot reset it " You can only reset your license 3 times within 12 months, it appears you have exceeded this limitation and the option to reset your license is no longer available. If you are having issues with your license and need further help please click here to log a request with the support team."

I have also tried "Deactivate offline", but it did not work

How can I do?
