Business Acrobat Pro DC license is not recognized

Hi there. I've purchased an Acrobat Pro DC licence for one of my employees, and whenever she logs in to the Adobe website, it tells her she does not have a licence. I installed the software to her computer via Creative Cloud, but it is still marked as a trial version.

I have checked the https://helpx.adobe.com/download-install/kb/activation-deactivation-help.html page and none of those issues apply to her computer or our network or licences. I have also tried to pull her licence and then reassign it, but although she receives the 'unlicenced' email, she never receives an email telling her how to activate her licence. I have exhausted all the options I can think of.

Could someone please offer a suggestion, or contact me regarding this issue? The "Contact Us" button in the Support drop-down menu doesn't link to anything.

Thanks.
