I've spent a fair few hours trying all sorts of methods to get this game running and so far i've had no luck.
As soon as i open the game and it gets to the logon screen it will immediately stop working and crash to desktop.
I've attempted reinstalling, changing files names so steam reacquires them, giving admin rites, running compatibility mode, updating drivers and changing the default graphics card used to make sure it's taking the 980 GTX.
The times it doesn't crash (this seems to be dependent whether i launch from the files or steam), i get to the log in screen but with constant network errors.
Any advice would be greatly appreciated but i'm starting to lean towards "wait on new build and come back later"
From what i have played so far though, even in it's base state, loving the game! Keep up the good work Devs!
