Can't deactive acrobat pro from old device to install serial number on new device

Hi all, I have see some threads on this and I was able to use this link to close the session on old laptop but I still can’t activate the license on the new laptop. It’s for Acrobat X Pro https://account.adobe.com/security/

I bought a new laptop - old laptop dead and in bin so can’t deactivate and getting the  actvation limit reached. Tried online chat - no help, tried calling and the wouldn’t help as don’t provide support on old one off products as we know as they want you to buy a subscription. Totally not worth that. They told me to post in this community to see if someone could help!

Any other ideas.
