Animator.GotoState: State could not be found.

Okay, so i got this code (C#)

 using UnityEngine;
 using System.Collections;
 public class Stats : MonoBehaviour
 {
     public float Health;
     public bool Dead;
     private bool Invencible;
     private float Counter;
     private Animator Animator;
     public float DeathCounter;
     private bool AnimPlayed;
     private bool MovementDisabled;
     void Start ()
     {
         Animator = gameObject.GetComponent<Animator>();
         DeathCounter = 6;
     }
     void Update()
     {
         if (Health > 100) { Health = 100; }
         if (Health < 0) { Health = 0; }
         if (Health == 0) 
         {
             Die();
         }
         if (Invencible)
         {
             if (Counter <= 0)
             {
                 Invencible = false;
             }
             else
             {
                 Counter -= Time.deltaTime;
             }
         }
     }
     public void DealDamage (float Damage)
     {
         if(!Invencible)
         {
             Health -= Damage;
             Invencible = true;
             Counter = 1;
         }
     }
     private void Die ()
     {
         if (!MovementDisabled)
         {
             Dead = true;
             MovementDisabled = true;
         }
         if (DeathCounter <= 0) 
         {
             Respawn();
         }
         else
         {
             if (DeathCounter <= 5)
             {
                 DeathCounter = DeathCounter - Time.deltaTime;
                 if (!AnimPlayed)
                 {
                     AnimPlayed = true;
                     PlayAnim("Dead");
                 }
             }
             else
             {
                 DeathCounter = DeathCounter - Time.deltaTime;
                 PlayAnim("Idle");
             }
         }
     }
     public void PlayAnim(string Name)
     {
         Animator.Play(Name, 0);
     }
     public void Respawn ()
     {
 
     }
 }

And this animator (Please, tell me the animator navigation controlls)

But, anywhere in the code, when i try to play the animation "Dead" using

 Animator.Play("Dead", 0);

it runs, and 2 seconds later (The code line is not even being executed)

Animator.GotoState: State could not be found UnityEngine.Animator:Play(String, Int32) Stats:PlayAnim(String) (at Assets/Systems/Character/Stat/Stats.cs:79) Stats:Die() (at Assets/Systems/Character/Stat/Stats.cs:67) Stats:Update() (at Assets/Systems/Character/Stat/Stats.cs:25)

The thing is, the animation plays fine. But the error makes me mad. With other animations it works perfect, and, i even tried playing the animation from other script, and, it don't shows any error. Is this a bug, or am i doing something wrong? Unity hates me. Thank you, and sorry for my english.
