First off, rename the mod folder once it's in the BeyondtheSword/Mods folder so that we will have different mod folder names there. All players need to name their mod folders as the player who sets up the game and those names need to differ for your game and mine.
As for what's causing a crash... I'm not sure BUT I have a suspicion. Koshling may know what he did to setup the first turn so that it's not trying to automatically send the game save by email but rather saving it to the right spot in My Games. I'm almost certain not taking a step to achieve that is what's causing the hangup.
@Koshling: do you know what we need to do to get the first turn started correctly?
If he hasn't answered, I'll be working on this myself this evening so maybe I can sort it out.
