Upgrade Studio 2022 - 2024 : error

Hello,


I tried to upgrade my license from Trados Studio 2022 Professional (desktop) to Trados Studio 2024 Professional desktop, but I got the following error message : 

Error message displayed on the Upgrade Licenses page: OOS system has failed to upgrade the licenses due to invalid expiry date. Instructions to return to licenses or use support are provided.
This after having problems deactivating online ...

Can someone help me ?
Thank you very much.

Christelle
