When I try to edit PDFs, I keep getting a notification that my serial number

 

is already in use by the maximum allowed computers. You must deactivate another computer or provide another valid serial number to use Adobe Acrobat again on this computer,

 

but the computer I'm using is the only one logged into my account. 

 

What is the best way to proceed?

It sounds like an old version of Acrobat that was previously installed on multiple devices.

 

Do you have a paid Creative Cloud All Apps plan?

If yes, you should have access to the latest version of Acrobat Pro DC.  No serial numbers required.
