Hello Denis Ahmedov

I`ve checked your account and you have a 2021 license. Studio 2019 should work if it`s installed on the same computer where Studio 2021 is installed as described in this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0033843

You can try the below steps: 

1. Close Studio.
2. Go to: C:\ProgramData\SDL\SDL Trados Studio\Studio15\Data
3. Rename the file Studio.lic, e.g. to Studio_old.lic.

Note: If you can't find the path above, open Windows File Explorer, click on View and check "Hidden Items" checkbox.

Thank you,

Sorin
