I recently bought a new laptop and loaded CB2018 on it. I was having issues with the laptop so I sent it in for repair. They ended up just replacing my laptop, so now have registered my license key on a laptop I know longer have. How do I invalidate that key so I can use it again?

Thanks!

Just contact support from the link in this forum or the main menu and they will do it - provide the order ID if possible or at least the email address you used when buying
