Can't activate Nitro Pro11

[Rimas631]

The license is valid but I cannot activate the product after the system upgrade.
The same message all the time: "The serial number entered does not exist."

If you are interested in upgrading your license to Nitro Pro 13 with VIP Access (formerly Software Assurance), kindly access our Upgrade Portal and enter your Nitro Pro 11 serial number: https://www.gonitro.com/pro/upgrade 

You should then receive an email confirmation with a new serial number to activate Nitro Pro 13.
