I have a problem. I have just found out about this site, and I have downloaded a couple modpacks, but none of them seem to work. When I go to Advanced>Load a Mod and I select it the game begins to restart, but when it is loading a window comes up saying "Civ 4 has encountered a problem and needs to close." It askes me to send an error report, but that hasn't helped. Any suggestions? By the way I don' own any expansion packs and I am pretty careful to look for the mods that don't require an expansion pack.

Which mod?

also please post the error it wants to send - click on show report instead of send it and post the upper part of that error message
