License deactivation after Installing Windows 10

Hello,

I have a problem deactivating my Passolo 2018 and SDL Trados Studio 2019 licenses.

IT installed Windows 10 on my computer and I forgot that I had to deactivate the licenses before the new installation of Window 10 on the old computer.

Now I can't deactivate the licenses to get new ones. What do I need to do?

Thanks,
Klaus
