Wim Mulder Posted May 18, 2022 Report Share Posted May 18, 2022 I have got an e-mail from you with a special offer for an advantage for upgrading before May 13th. Serial Number: 504981-xxxxxx-xxxxxxxxxxx I have Nitro Pro 188.8.131.523, and I wish to upgrade to Nitro Pro 14 When I click to "Buy Now" I have to fill in my serial number on your site. Then I click: "Get Upgrade". After clicking I got the message: "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." Because I have a new computer I have deactivated my serial number. And then I expected It would be possible to succeed if I try again. But it wouldn't luck. Please can you help me. Link to comment Share on other sites More sharing options...
