I have no idea what that means and havent seen that before ever.
Some additional info: I tried to play an online multiplayer skirmish and for a second this popped up. A split second later was another new one (see list).
@GPG and Stardock: Can you give us a short description on what some of the error messages mean, please.
And it seems the new error messages are working fine. Still no connection to other players but hopefully they help to narrow down the problem(s).
Guys, if you encounter a new error message, please post it here too, I'll make a list.
List:
1. A token provided is invalid.
2. Failed to get game info.
