Well i just solved my own problem thanks to FO4Edit. It seems that my creation was depending on some mod and, as that mod is .esp and not .esm, it wouldn't work. Now just a question. If i change that mod to .esm instead, it would accept my modifications? EDIT: Also i want to add a debuff that start running when the buff runs out, like fatigue and others, is it possible? EDIT2: Aaalso... i would like to know if its posible to make that only one kind of this buffs can be active at same time. I meant if that you use a second buff (different than the first but uses almost same materials) it replaces the first one you took. Sorry for so many questions. And sorry for my english i know its bad.
