Enemy not following player.

If you've seen my previous answer, this is sort of a followup on a different subject. I have a character (enemy) made in Blender and exported each individual mesh into a separate .obj file. after doing this, the enemy no longer follows the player. Here is my script:

 using UnityEngine;
 using System.Collections;
 
 public class ExperimentalEnemy : MonoBehaviour {
 
         public Transform target; 
         public int moveSpeed; 
         public int rotationSpeed; 
         public float noChaseRange = 50f;
         public int HitBoxRadius;
         public ExperimentalDeath Damage;
         public float Health = 10f;
         private Transform myTransform;
         public GameObject Char;
         public Animator EnemyAnim;
         public GameObject Poof;
         public bool isDead;
         void Awake() {
             myTransform = transform;
         }
         
         // Use this for initialization
         void Start () {
             GameObject go = GameObject.FindGameObjectWithTag("Player");
             
             target = go.transform;
 
             isDead = false;
 
             Char = GameObject.FindGameObjectWithTag("Player");
 
             HitBoxRadius = 4;
 
             
 
 
         //Reference to DamageChar from the ExperimentalDeath.cs script
         Component Damage = Char.GetComponent<ExperimentalDeath>();
 
     }
     
     // Update is called once per frame
         void Update () {
             if (Health < 0.1) {    
 
                 isDead = true;
 
                 EnemyDie ();
             }
             Debug.DrawLine(target.position, myTransform.position, Color.blue);
 
             if (isDead == true){
 
                 Health = 0F;
 
                 Destroy (collider);
 
                 if(Random.Range(0f, 20f)< 1){
 
                     Instantiate (Poof, transform.position, transform.rotation);
 
                 }
 
             }
             
             if (isDead != true){
 
                 //Look at target
 
 
                 transform.LookAt(target.position);
 
 
                 if(Vector3.Distance(target.position, myTransform.position) > noChaseRange) {
                     //Move towards target    
 
                     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
                 }
                 
                 if(Vector3.Distance(target.position, myTransform.position) < HitBoxRadius) {
                     Damage.DamageChar(Random.Range(0.01F, 0.2F));
                     Debug.Log ("Is Damaging " + Char);
                 }
             }
 
         }
  
     public void EnemyDamage (float amount) {
         Health -= amount;
     }
 
     public void EnemyDie () {
 
         //if(Random.Range(0f, 10f)< 1){
         //}
             Destroy (gameObject, 2F);
             EnemyAnim.SetBool ("Die", true);
     }
 
     void OnTriggerEnter (Collider other){
         if (other.gameObject == GameObject.FindGameObjectWithTag ("Bullet")){
             Destroy (other, 0.1F);
             EnemyDamage(Random.Range(0.1F, 0.2F));
         }
     }
 
 }
