deactivate my licence of Trados 2021

Question

I would like to deactivate my licence of Trados 2021 in order to upgrade on Trados 2022, but I get error messages in both ways, trying to deactivate the licence online or with the offline deactivation. I tried several times, but don't succeed. 
 Hope you can help me...Thank you so much for your reply in advance! 
 
 Hope you can !
