SDL Trados 2021 ask to enter the licence again and I cannot deactivate either online/offline

Good afternoon,
With your help in resetting my licence, I had successfully activated the licence for SDL Trados 2021 onto my new computer last week. 
However, today my SDL Trados 2021 on the new computer prompted a message asking me to re-enter the licence again and not allow me to work on the current project.
Would you please help me with this issue?  Thank you.
Kind regards,

Marco
