Error -23 on activation but licence active

[Marcom 0]

I deactivated nitro 12 on the old one and tried to reactivate it on the new one.
Activation reports error 23.
I only have one pc activated, but I can't activate it on the second one anymore.
I can provide the license code separately.
Can you help me?

Hello @Marcom,

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

Since I am unable to pull-up your account, could you please provide the serial number of your Nitro Pro 12?

Thanks and I am looking forward to hearing back from you.

Hello @Marcom,

Thank you for the private message.

To further assist you, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Cheers!

Thank you very much!

Now the code works!
