The Mod wont work ! HELP !

[Ludens]

Hello The Arabian, welcome to the .Org .

I am afraid the creator of the mod is longer active on this forum. I am not much good at Tech Support, but I do know that The Crusades requires R:TW + Barbarian Invasion expansion patched up to v1.6. If you have the Gold Edition of R:TW, it will already be v1.6 when you install it.

Thanks for the welcoming Ludens.

Alright then, Do you know any other mods that is about the crusades ?

There was a competing project called Crusader: TW, but that was never released. There are two other medieval mods, although I don't know if they include the Crusades: Chivalry: Total War and Rome Medieval.
