Ever since patching to the current level (403 or something like that) I cannot host a multiplayer game online, even saved games which were previously multiplayer.

What happens is that the leader list shows the top leader as me. That is, my Triumph registry, instead of Human 1. All the other leaders are shown as AI. If I change one of them to me (again, only my screen name is an option, not Human) then the top leader changes to AI.

I read the sticky thread "STICKY: How to play multiplayer", and even though the OP was edited to say that it was only for AoW there was some discussion in there on AoWIII about needing to be on Classic Turns. Which all of my saved games were, and I've tried starting a new hosted game as well, and toggling the setting to simultaneous and back on my saved games, and I still have the same issue.

Any assistance will be greatly appreciated!

It appears as though this is a change brought about by the new version, and that "Human 1", "Human 2", etc. are no longer used. When my friend tried to join the game it changed the top AI leader to his Triumph username and we were able to play.
