I just tried this game today. There's four options. I have windows so I tried the Windows launcher. that one said I can't connect to server. - I then found somewhere saying I need to use the Installer if on PC. I did that. It installed correctly.
I then loaded the installer, but now it's jsut stuck on a screen with a wolf guy and a 0.00GB/0.00GB thing. A play button all greyed out.
