Newbie Question -TGC 2019 Interface

[Rarneybubble]

I bought a complete used system and just transferred the TGC license ownership. In the TGC Skytrak Interface there is a box called License Key. There is already a string there, but I think it may be the previous owner's key. Do I need to Deactive the one already there and copy my new TGC license key. I also copied it in the TGC Simulator Console ang i am now the owner. Should the key in the console and the key in the interface match?

Just don't want to screw anything up and want to start playing!
Many thanks
