Unable to deactivate my Studio 2019 Network licences

Hello,

We recently purchased upgrades for our 5 SDL Trados Studio 2019 Professional Commuter licenses, to upgrade them to the 2021 version. When I try to deactivate them on the SDL License Manager to apply the upgrades, I get the following error message:

 

Provider error occurred, code: 0.

Revocation is not allowed for an expired license.

 

Yet, in the WlmAdmin console, all my licenses are active and have no End date. Is there a way around this?

 

Thanks a lot in advance.
