Helping to disable rekordbox licence key

Hi. I heard that a single rekordbox licence key enables one to use it on 3 different computers.

You see, I reformatted my computer without disabling the rekordbox licence key. Thus, in my Pioneer account, I could see that the key is still active on that computer.

Is there anyway to disable that rekordbox licence key so that I can use it on my computer that has reformatted?

Thanks!
