I just checked with both the down loader and also using the WiFi web interface and the Hexcode web system is working correctly so if you still have a problem it would seem it is other than the Hexcode system
I'm sorry, I never checked the download again today before responding.
I assumed the problem was still present since people reported the same symptoms but you are correct, the server is responding normally now.
To anyone still having problems, begin with checking if it is your firewall and/or antivirus software that is interfering with the connection.
Just try and its work now, might be a new year gift.
Happy new year.
