Against the Wall will not run on my system. It causes Civ4 to stop responding. I've played (* to completion) several scenarios without trouble: Grand Menagerie* The Momus Barbarian Assault* Gift of Kylorin* When I choose Against the Wall it never leaves the scenario selection screen. After a few seconds Windows7 minimizes the game to alert me that it has stopped responding. Does anyone have any suggestions for getting it to work? Failing that, is there a way to transfer the list of trophies achieved and scenarios unlocked to another machine? If I could do that then I could play that scenario on another computer, unlock the last scenario, and then move back to the original computer. Thank you for any assistance.
