I'm currently on Version 6 and would like to upgrade to 12 but get an error when entering my license (does not have serial number) number. Please advise ...

Hello @zanewinston,

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

I was able to find your account but it does contain your Nitro Pro 6.

For me to further assist you, kindly send me a private message and provide your Nitro Pro 6 serial number.

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