Unable to download .exe file after receiving .lic file

[t0x-1k]

Hmmm… can't reach this page
update1.nextron-systems.com refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

** I have removed all windows defender software with the same effect. I have used both bing and firefox with the same result.
I have an email with the .lic file and a link to download the lite file. Is there something I am missing?
