No connexion possible with Multiterm using Studio 2019

I was working yesterday on my file. This is a job I am on it since 2 weeks and everything went fine. Yesterday as I wanted to add a term in the Terminology Database, I got a message it wasn't possible but I could add it in an other Terminology Database, so I was fine. I close Studio at the end of the day.

This Morning, I opened Studio and the file but I get a message that the terminology database can not be connected to Multiterm. The database has been created with an other version of Multiterm and cannot be open. This is very Strange as I didn't updated anything since I an working on this file. 

I Don't know what to do, can somebody help me ?

I am working with Studio 2019 SR2 15.2.0.1041

Multiterm 2019 15.0.5.56289

Windows 10
