I have played over 600 hours of Fallen Enchantress and Legendary Heroes. It embarrasses me to admit it, but there it is. During that time, I have experienced constant CTD's, one out of every 20 or 30 minutes. I put up with them because I like the game so much, and without more information, I didn't think I could provide enough that would prove helpful in determining the source of the problem, though it did appear to occur during the autosave process. Well, I finally experienced a CTD that provided some information that could be useful to you. I got a CTD and when I tried to restart the game, I got the message that DataZip.exe was not operating correctly and I was returned to the desktop. When I rebooted that particular problem went away. Here are my system stats. Windows 7 Home Premium, Service Pack 1, Intel i3 dual core processor 2.93 GHz, 3 GB RAM, 32-bit Windows. I don't know if this is relevant, but I installed both of the DLC's yesterday. I hope this proves helpful.
