how to unregister Cubase LE

I want to sell my interface (Tascam US1800). I need to unregister a copy of Cubase LE that came with the unit but I don’t have my computer anymore (died like 2 months ago). I see it in my list of things on my account but it only has a “software Reactivation” button. Is there a Software Deactivation button?? Cheers, Lucius
