Monster doesn't move

I'm very sorry that I have to ask this, but I've been trying & looking up answers for about the past 5 hours now on something so simple... I have a spider that has to chase my player, without using Translate cause the map has depths and walls. I have this code

 Debug.DrawLine (target.transform.position, myTransform.position);
     //Look at target
     myTransform.rotation = Quaternion.Slerp (myTransform.rotation,Quaternion.LookRotation(target.position-myTransform.position),rotationSpeed*Time.deltaTime);        //move towards target
     //myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
     //Vector3 direction = transform.rotation * new Vector3( 1 , 0, 0);
     //Vector3 dist = direction * moveSpeed * Time.deltaTime;
     myTransform.TransformDirection (Vector3.forward);
     cc.SimpleMove (myTransform.forward*moveSpeed);    

and I've also tried some other ways of translating the vectors, but whatever I do it doesn't move ( it finds the enemy and aims for it though...)

Could it be because it's instantiated by the photonnetwork? I'm at the last of my resort...
