Language Weaver Cloud Provider not working

Good afternoon,

I have a problem with the Language Weaver. Infact I inserted it in the Project Setting -> Translation Memory and Automatic Translation, but I get the message that there is No model available for the language pair (British English --> French)...

I don't understand what is the issue, since I normally used the Language Weaver until last week without any problem.

Thanks 

best regards

Silvia
