License problems in Trados 2019

Although my license is correctly paid, if I put it in my Trados application it cancels the possibilty to create a new project or open an old one.

It's very weird because if I deactivate this license and use the app in free trial mode it give the chance to open or create a project again.

Do you know what happen?

Thanks.

The error message is:
'This feature is not available in the Studio Edition you are using. Please upgrade you license to enable this features.'
