Deactivate licence to re-install Trados Studio Freelance 2015

Hi,

I am a recent user of Trados, just go it last week and had to install it on a virtual machine on my mac and Windows 10 and so on...

Anyway, my computer had a problem, i could not edit any file again on Trados and decided to re-install it on another virtual machine.

Therefore I suppressed Trados without deactivating it (not smart I know). Now I want to re-install but obviously my product key is still in use !!! So i am stuck.

Can someone please help me, I have so much work to do, I am so late!

Kind regards,
