Game starts, then gets stuck on turn 0

Noticed something new today. Tried this three times, with less mods active and after clearing cache:

Game starts, with the selected civ. Opening screen shows, with active unit (Settler). Cursor is there, but the screen looks frozen and my cursor doesn't do anything. Exiting the game is impossible. Trying Ctrl-Alt-Del temporarily shows the Manager, then the screen goes back to a black Civ screen. I can only restart my computer (by pulling the plug) because the whole PC is now stuck. Any suggestions would be most welcome.

Update: uninstalling and reinstalling the game has no effect. The issue must be related to a mod, but I cannot pinpoint which one (except that it's not a civilization mod). I'd just been playing 40sw4rm's Old world mod with no problem (which I now cannot start anymore). The issue first appeared when I wanted to start an YnAEMP game. Simply starting a Single Player game gives no problems.
