My Nitro version is I've been using it for 8 month.

Then, after a regular Windows 10 Update Nitro Pro stopped working. Error - Proxy settings are incorrect.
All attempts to reactivate my license failed.

My license status shows

Serial Number 50XXXXXXXXXXXXXX01
Version 13
Status Active
Number of Activations 0
Number of Activations Allowed 2

Please let me know how to proceed.

I hope this helps! Please let me know how that goes.
