License problem

hello there, i have upgraded my laptop and now can no longer use marginnote despite entering the correct license code on devmate. It tells me i am unable to use it on a new computer even though it is wiped from previous.
Can you help?

Hello, joebtay,

Welcome to the MarginNote Forum.

My macbook was broken up and then logic board has replaced.
So I can not ‘deactivate’ now.
About this problem, I sent e-mail to with license code, but I didn’t receive any mail yet.

Please help me!

Hello, thank you for your response.
I wiped my laptop, disconnected icloud and reinstalled Mac OS, and have now traded it in- no idea had to be uninstalled in this situation.
Is there another way to reactivate my app?

Hello Hong & joebtay,
Could you please tell me whether your code is bought from fastspring or paddle?

I have no idea about that, but the order mail came from ‘’.

So I think I bought it from fastspring.

When i put in the code, it is recognised by devmate but not paddle.
I received a single use coupon for fastspring
