[Giuseppe Petrolati]

Good afternoon, system does not recognize my serial number. I tried many time.

Thank for replay.

Hello @Giuseppe Petrolati,

Thank you for reaching out to us through our Community Forums!

To further assist you, could you please provide the serial number of the Nitro Pro you would like to upgrade?

Thank you very much in advance and I am looking forward to hearing back from you.

I encounter the same problems as Guiseppe Petrolati, what was the solution? Thanks for your help in this matter.

Hello @Richard Fierkens,

Thank you for reaching out to us through our Community Forums!

If you can also provide the serial number that our Upgrade Portal is not recognizing, I should be able to see what is happening.

Is this possible in your next response to this thread?
