Deactivating SDL Trados 2019 and updating to SDL Trados 2021

Question

Hi, I'm having problems with deactivating Trados 2019 - when I try to deactivate Trados 2019, a message saying "Login for this product has been restricted. Contact the system administrator for assistance" appears. What should I do? 
 Also, when I open my SDL account sdl.com -> product & plans -> licences I can only see licence for SDL 2021 freelance plus (not my previous 2019 freelance plus licence). Could you help me please?

Hello Šárka Juříková 
 This happens because your 2019 license was upgraded to 2021. 
 When you processed the upgrade from 2019 to 2021, the 2019 license was removed from your SDL account as per this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0039975 
 Is there a reason you want to deactivate Studio 2019? 
 Thank you, 
 Sorin
