You emailed on March 16th, then our helpdesk replied to you, then you responded to them again? It looks like you are using another firewall, so it blocked our own app from activating. Is it possible to allow GlassWire to connect so it can stay activated?
Make sure your firewall has a rule for activate.glasswire.com. I had a similar issue until our proxy server and firewall allowed this traffic.
Also if your key continues to deactivate, make sure your computer is sleeping correctly. My theory is that I was off the network too long and got too many “License verification failed” events which would auto-deactivate my key.
