Hello ABG,
To add to Carey's post, I would recommend using the contact information provided in the link and they should be able to point you in the right direction regarding your licensing questions as well as seeing if it would be possible to block the product key. They should be able to provide you with a replacement software and product key as so you will not have to worry about any licensing issues. Please let me know if you have any further questions or concerns.
Thank you,
