See in the error, it says that mount&blade.exe is failing. the exe is usually the thing that actually starts the program. But for some reason, all my downlaoded mods work. But it tells me the loaction of the problem, and its not in my mod, which is what confuses me the most. Ive talked to guspav, who is an experienced modder, and he says it might have something to do with an name for an item mesh i did, but im not sure.
