Upgrade Issue - "We were unable to validate your serial number."

[Iulian Costache]

Hello everyone!

I have tried to do an upgrade from v13 to v14 but when I insert my serial number into the site, it comes back with this error:

We were unable to validate your serial number. Please ensure you entered it correctly. If you believe you are eligible for an upgrade, please leave a post on our Community Forum and update us with your issue.

Anyone here could help me out?

Thank you in advance for taking the time to work with me on this!
