Acrobat Pro license keeps showing as a trial version

Thx for your suggestions

It didn't work though, I fixed the problem by changing the users laptop to a new one

It's probably not the user, but the computer. 

I would do the following tests:

• having a different user with an Acrobat licence logging into the laptop, and activating Acrobat.
• having the user loging into a different computer and activating Acrobat.
