@Trotski12 My guess would be corrupted downloads or bad installations of the mods that didn't work. You should troubleshoot a mod individually. When you group them all together as you did and then ask for help, it's difficult to assist you. Specifically, I have the BKB Supermod, XL, Fall of Rome, and MedMod installed and they work fine for me. The BKB installation is a little tricky. You install the mod BKB 2.0 to your Total War folder NOT the Medieval - Total War folder. The BKB 2.1 patch does install to the Medieval - Total War folder, if I remember correctly.
