My Machine Translation stop working

Hello, 

My Machine translation suddenly stops working. 

It appears on my project configuration but when I want to use it on the document, no results. When I select the option before it appears the language pair but no more.

I already went to my subscription plan and think still have available characters.

I have Trados Studio 2021.

Do I have to re-install Trados? 

 

Thanks for your help.
