[Unity 5] GetAxis("Horizontal") Causes player to move the opposite direction

http://answers.unity3d.com/questions/550988/my-movement-keys-are-opposite-to-actual-movement.html

My issue is exactly the same as in this thread. In my code, the player can rotate. this part works as desired. I can move vertical just fine, but horizontal movement makes me move the opposite direction (e.g. I move right when I press left) My code is this: using UnityEngine; using System.Collections;

 public class PlayerController : MonoBehaviour
 {
     private float speed = 1f;
     public Transform playergraphic;
 
     void Update()
     {
         ControllPlayer();
     }
 
     void ControllPlayer()
     {
         float horMovement = Input.GetAxis("Horizontal");
         float vertMovement = Input.GetAxis("Vertical");
         if (horMovement != 0 && vertMovement != 0)
         {
             speed = 3.0f;
         }
         else
         {
             speed = 1.5f;
         }
         transform.Translate(transform.right * horMovement * Time.deltaTime * speed);
         transform.Translate(transform.forward * vertMovement * Time.deltaTime * speed);
 
         //Player graphic rotation
         Vector3 moveDirection = new Vector3(horMovement, 0.0f, vertMovement);
         if (moveDirection != Vector3.zero)
         {
             Quaternion newRotation = Quaternion.LookRotation(moveDirection);
             playergraphic.transform.rotation = Quaternion.Slerp(playergraphic.transform.rotation, newRotation, Time.deltaTime * 8);
         }
         //Player graphic animation
         /*if (moveDirection.magnitude > 0.05f)
         {
             playergraphic.GetComponent<Animation>().CrossFade("walk", 0.2f);
         }
         else
         {
             playergraphic.GetComponent<Animation>().CrossFade("idle", 0.2f);
         }*/
     }
 }

I have tried multiple "solutions, but nothing works. I can manually force input from keys, but this kills the option for a controller, and would make my investment in one for testing reasons a waste. Is this a issue in the latest build of Unity 5?
