It doesn't really matter as the license is to the named user and can be put onto a number of machines for the moment.
The only thing that can be done is to cancel that license and issue you with another one.
However, we only have your word that you are who you say you are and that you could be trying to cancel the license for the rightful owner.
There's nothing really to do here, but how did your license come to get hacked ?
