DECTIVATION FAILED message. Impossible to deactivate on my desktop pc and I need it active on my desktop within this morning!

I urgently need to transfer my Trados 2017 license from my PC to my laptop now to be able to complete the urgent delivery of an important project.

I proceeded as usual online but received a "Deactivation failed" message. Tried again, but it was impossible to continue.

Then tried to deactivate offline. But when I tried to paste the "deactivation certificate" in Trados I have received the "Deactivation failed" message again. However, now my license is Deactivated on my PC. 

I then tried to activate the license on my PC with my activation code, but received the message "Activation failed. Please provide a quantity less or equal to your remaining quantity of zero" !!

I did not change anything in my Windows 10 PC system since last activation. Did not even install any new app.

Now it is almost 3 am Central European Time, and I need to go to sleep and to be sure that I can have my Trados license active on my desktop by tomorrow morning. I have been using and upgrading Trados licenses constantly since 2001 and I never had this before.

Please notice that if not fixed in time, this is going to create a case of significant financial damages.

I look forward to receiving your timely reply.

Faithfully,
