This is the first time I've gone beyond the 2050 time victory, as I'd been building an invasion force to take on India so I could get a bit of experience with fighting a Civ with equal tech and some modern units. CtD each time I click Next Turn, on turn 1516. Please See my save game and see if you get the same. System Spec: Intel E6600 @ 3.2GHz 2GB RAM @ 1600MHz HD4850 512MB XP SP3 (So, DX9) 1280x1024, 60Hz, V-Sync On Patch 220.127.116.11. I've not had a single CtD since I've had the game (which I got on UK release) and it runs very well on my system, with the exception, of course, of all the bugs the game has. Thanks!
