Unity import manager not working properly

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerMovement : MonoBehaviour {
5.     //public variables
6.     public float acceleration = 5;
7.     public float decceleration = .2f;
8.     public float gravity = 21;
9.     public float airAcceleration = 2.5f;
10.     public float jumpAllowTime = .1f;
11.     public float wallJump = 10;
12.  
13.     //Private variables
14.     float curSpeed;
15.     float jumpAllowTrack;
16.     float moveSmooth;
17.     CharacterController cont;
18.     bool run = false;
19.     Vector3 curMove;
20.  
21.     //Smoothdamp variables
22.     float walkMoveV;
23.     float runMoveV;
24.     float stopMoveV;
25.     float airAccelerationV;
26.     private Stats Player;
27.  
28.     //Get that stats
29.     void Awake (){
30.         Player = GetComponent<Stats>();
31.     }
32.     // Use this for initialization
33.     void Start () {
34.         cont = GetComponent<CharacterController>();
35.     }
36.  
37.     // Update is called once per frame
38.     void Update () {
39.         //sprint and movement.
40.         if(Input.GetKey (KeyCode.A) || Input.GetKey (KeyCode.D))
41.             run = true;
42.         else  
43.             if(run == true && Input.GetKey (KeyCode.LeftShift))
44.                 curSpeed = Mathf.SmoothDamp(curSpeed, Input.GetAxisRaw ("Horizontal") * Player.runSpeed, ref runMoveV, moveSmooth);
45.      
46.         else if (run == true)
47.             curSpeed = Mathf.SmoothDamp (curSpeed, Input.GetAxisRaw ("Horizontal") * Player.speed, ref walkMoveV , moveSmooth);
48.      
49.         else
50.             curSpeed = Mathf.SmoothDamp (curSpeed, 0, ref stopMoveV , moveSmooth);
51.      
52.      
53.         if(Input.GetButtonDown ("Jump") && jumpAllowTrack >= 0)
54.             curMove.y = Player.jump;
55.      
56.         // the actual movement
57.         cont.Move(curMove*Time.deltaTime);  
58.      
59.         curMove = new Vector3(curSpeed, curMove.y, 0);
60.         //Is it grounded?
61.         if(cont.isGrounded){
62.             //reset vertical movement
63.             curMove.y=0;
64.             // normal control
65.             moveSmooth = acceleration;  
66.             jumpAllowTrack = jumpAllowTime;  
67.         }
68.      
69.         if(!cont.isGrounded){
70.             // enable the gravity
71.             curMove -= new Vector3(0, gravity * Time.deltaTime, 0);
72.             //give less control in the air
73.             moveSmooth = airAcceleration;
74.             jumpAllowTrack -= Time.deltaTime;
75.         }  
76.     }
77. }

I have this code which has no errors and works just how I want it to, I reset the input manager so that it has all of the default settings, I've tried making a new input axis and no matter what the W and A keys do not work and I have to wait a few seconds before the left and right keys start working and i know it is not my keyboard because typing for everything works perfectly fine.

 

Nevermind fixed it by restarting the file.
