I just bought the Medieval 2 Collection through Steam and installed it. I then installed EB2 2.0.1 and then 2.0.3 and the graphical enhancement mod. When I tried to start a campaign the game crashed to desktop. I'm not sure where to find the crash log. I'm running Windows 7 64 bit.
Edit: The game also crashed when I was browsing through the factions on the grand campaign screen.
