Just downloaded the game and I'm unable to get past the title screen. Looks like it's attempting to get to the User Center for I assume account registration, but the popup isn't properly displaying for it. You can see waiting around doesn't seem to help, and closing the invisible popup with the X button gives a Silver Communication error (7004006).
I've already tried the Fix-button to redownload contents as well as verifying file integrity on Steam. I also tried two different networks on my PC and also with & without a VPN, but no luck.
