Game Freezing

My civ will no longer process games like it should with the new patch. I try to play a standard 8 player SP game, and with the new patch you can see (processing AI turn) at the bottom of screen. And it seems like around turn 60-70 once i tech Engineering, my game freezes, nothing works, i have to use Ctrl+Alt+Del to get out of the game.

Help please? Its happening in MP as well!!

I have the same problem. I am hotseating with my daughter. I am playing Earth, 42 City States and 14 Civilizations. I don't have a fix for you. What I have done is put my Autosave on 1. When the thing freezes on me, I restart the game and I am back one turn. I get these crashes at least once every time we play. Sending the developers the save file won't help, because, when I restart the game, it works again.
