Hey all,

We're aware the multiplayer servers are down and we're working on a fix. We'll keep you updated here:

If there's no indication that servers are down - which in this case there isn't - then this is an indication of a local failure to connect to the matchmaking server. Double-check your network, connections, and firewall, and see if there's anything useful in your log file found in (mydocs\my games\battlezone combat commander).
