New Movement Script Not Registering Keyboard Input

When I create a movement script apart from the ones included in the standard assets, in play mode the keyboard does not work. I have tried re writing the script and there are no errors. and when I try importing other scripts or using other tutorials, none of them work. This seems to only happen in Unity 5.1 and onwards. It seems to be an ongoing problem and all of the "remedies" that are detailed do not work. I have tried editing the registry as seen here "http://answers.unity3d.com/questions/372239/basic-keyboard-input-not-working.html". But I cannot find the Input registry key. I have also tried many other remedies to no avail.

Here is my script:

using UnityEngine; using System.Collections;

public class SpyController: MonoBehaviour { #region Component Variables Rigidbody r; Animator anim; CapsuleCollider capCol; [SerializeField] PhysicMaterial zfriction; [SerializeField] PhysicMaterial mfriction; Transform cam; #endregion

 [SerializeField] float speed = 4;
 [SerializeField] float turnSpeed = 5;
 [SerializeField] float jumpPower = 1;

 Vector3 directionPos;
 Vector3 lookPos;
 Vector3 storeDir;

 float horizontal;
 float vertical;
 bool jumpInput;
 bool onGround;

 void Start()
 {
     r = GetComponent<Rigidbody>();
     cam = Camera.main.transform;
     capCol = GetComponent<CapsuleCollider>();
 }

 void Update()
 {
     HandleFriction();
 }

 void FixedUpdate()
 {
     horizontal = Input.GetAxis("Horizontal");
     vertical = Input.GetAxis("Vertical");
     jumpInput = Input.GetButtonDown("Jump");

     if (horizontal == 0)
     {
         storeDir = cam.right;
     }

     if (onGround)
     {
         r.AddForce(((storeDir * horizontal) + (cam.forward * vertical)) * speed / Time.deltaTime);

         if (jumpInput)
         {
             anim.SetTrigger("Jump");
             r.AddForce(Vector3.up * jumpPower, ForceMode.Impulse);

         }
     }

     directionPos = transform.position + (storeDir * horizontal) + (cam.forward * vertical);

     Vector3 dir = directionPos - transform.position;
     dir.y = 0;

     float animValue = Mathf.Abs(vertical) + Mathf.Abs(horizontal);

     anim.SetFloat("Forward", animValue, .1f, Time.deltaTime);

     if (horizontal != 0 || vertical != 0)
     {
         float angle = Quaternion.Angle(transform.rotation, Quaternion.LookRotation(dir));

         if (angle != 0)
             r.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(dir), turnSpeed * Time.deltaTime);

     }
 }

 void OnCollisionEnter(Collision other)
 {
     onGround = true;
     r.drag = 5;
     anim.SetBool("onAir", false);
 }

 void OnCollisionExit(Collision other)
 {
     onGround = false;
     r.drag = 0;
     anim.SetBool("onAir", true);

 }

 void HandleFriction()
 {
     if (horizontal == 0 && vertical == 0)
     {
         capCol.material = mfriction;
     }
     else
     {
         capCol.material = zfriction;
     }
 }

}

I need help because any script that requires input from the user doesn't work.

Any help would be appreciated!
