To continue accessing the multiplayer services, we created an AgeIIIESOPatch_Full patch that points to a new backend owned by Microsoft. Due to the age of the title, we have no way to automatically apply the patch for you and you will have to come to our website download linked below to apply the patch manually. We apologize for any inconvenience this may cause.
One thing you may find interesting is that multiplayer seems to works fine between 2 m1 macs. I've played several games locally, via 2 steam accounts with separate licenses of the game, without any problems whatsoever, but I just tried to play a friend the next state over and the game crashed with that \"out of sync error\" after about 10 seconds of play no matter what game settings were used. 1e1e36bf2d
