Hi, I have deactivated my Nitro Pro License (234600-xxxxxx-xxxxxx) online but I've got -23 error anyway.

Thank you

Hello @playpiano,

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

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.

Thanks for choosing Nitro Pro and I hope this helps!
