Whenever I try downloading update, going to map editor, or logging on it says some kind of error.
Also make sure your firewall is set up to allow the patched version of Age3x.exe out to the internet. What I would do is uninstall everything, reboot, install age3, install TWC, install TWC patch milo linked too, add age3x.exe to your firewall exception list, and then try to connect.
It says this: There was a connection problem. Make sure you are connected to the internet and can access http://eso.com with your Web browser.
