Thank you for reaching out through our Community Forums!

I have taken the necessary adjustment to ensure that you can proceed with upgrading your existing license to version 14 through the Upgrade Portal.
Please access again our Upgrade Portal and try to upgrade that serial number. 

If the unable to validate message persists, please provide the serial number that you would like to upgrade. 

Kind regards,

I have the same problem as Mr. Demaree.  I've entered the 18-character serial number that I have for Nitro Pro 13, but the online form indicates that the serial number is invalid.

I hope that you can assist me also.

Thank you.
