Deactivate and activatee

I purchased SDL Trados  Trados Studio 2019.  I upgraded 2021 from 2019 free of cost.  2019 and 2021 both were in my computer.  I reset my computer.  2019 lost and all lost.  Again I downloaded 2021 Trial version.  I tried to activate.  But it shows in use in my license tab.  I reset but shows error.  Please help me how to deactivate as it was done before and reactivate my SDL Trados Studio 2021 Freelance trail version.  

Regards,
