Problem deactivation of a license of Trados Studio 2017

Hello,

I would like to use my extra-license of Trados Studio 2017 on another device, but when I try to deactivate it offline, I recieve the following error message: An error has occurred with your offline-deactivation. If you continue to have problems, please Please log a support request.

Can you help me with this problem?

Thanks a lot
