How do I move my key from my dead computer?

Hello,

My computer recently crashed and I am seeking to reinstall my Education licence. Unfortunately I wasn’t able to disable the key on my old machine, which means I can’t enter my valid education key onto my new computer.

Is there any way I can disable the old key? Or swap keys so that I can use the Education licence on a new computer?

Cheers!
