Connecting to Conflux.

Hey everyone, does anyone have Conflux working properly? I wanted to start playing through the campaigns again; the last time I played was in the fall of 2014 on Windows 7 x86, and I didn't have many disconnect issues with Conflux. I could play for several hours without being disconnected from the server. Now I'm on Windows 8.1 x64, and I can't even play for two minutes before I get kicked back to the main menu with a message saying that the network connection has been lost, and I've been disconnected from Conflux. I've searched the internet, tried running the game with an open browser logged into the Conflux website, completely uninstalled the launcher, cleaned the registry, reinstalled it from scratch, set compatibility mode, opened all the ports, ran it as administrator, and added the Ubisoft servers to the hosts file, but nothing helps. Is it now only possible to play the campaign in offline mode without all the benefits of the Dynasty edition?
