I have mentioned this in another thread, but just to have the topic and possible solution in one place, I will make a post about it here.
The issue: After pressing Play and the matchmaking timer starts. The screen fades out and the running rabbit loading screen appears.
This continues and only alt+F4 can remove you from the game.
Chances are that the connection issues will be fixed with a patch. Just a post to record the issue.
Just for funzies though
We couldn't even get a game with six players
