Reinstalling Cubase elements 7 on new PC

Hello!
I have upgraded my PC a bit which meant reinstalling Windows.
Now Cubase is not installed and I did not uninstall it before I remade my PC.
Now when I try to install cubase it says that my Licensing key is already being used… on my other motherboard that is in the trash right now. For activation I use the eLicensing service. How do I deactivate Cubase on my old PC so that I can reinstall it on my new?
Tankful for any answers. Cheers :smiley:
