Same issue here. I can see windows ran an auto update 2 days ago, but the game was working fine when I last started it only a few hours ago.
I wonder if this is network related - it does mention this occurs when communicating with the server.
Further info:
Windows 10 steam install.
When booting the game, all loading screens appear as normal.
As the big ant logo and drum sound (?) appear before the main menu screen the sound of the error window popping up can be heard.
The main menu is not loaded, instead the error mentioned above appears at the bottom left.
Pressing A on the controller for "OK" just re-loads the error window.
This occurs when I believe the usual copy protection check is done online.
Can confirm my PC is online when this occurs.
Can confirm windows is up to date.
@HBK619 or someone from bigant - any suggestions?
