Ok, I'll get to the point: about a week ago, Civ stopped working on internet multiplayer (I have not tested lan connection). Singleplayer works fine. But when I get invited to a game to play with my one of my friends, it will be on the normal multiplayer menu with the nation list and server info, and then after a while (sometimes when the game is started and you have your opening dialogue about your nation, sometimes even before the game is started) it will crash. I took the liberty of creating a paste on pastebin out of the crash log: http://pastebin.com/71zZ5wLS Any help would be appreciated :)
[EDIT] The game we are using is a PREVIOUSLY existing game that we have played on before and experienced no technical issues.
[[EDIT]] I think we fixed it. We started a new game and it worked perfectly. I suspect that the game save file was corrupted (or something similar), as my friend was getting visual C++ errors when he tried to load his single player games as well. I'm still not entirely sure, so I would like to have a definitive answer so I can avoid this problem in the future.
