Unity 4.3 Animator has not been initialized.

Hi folks, I am making a 2d game. At start my char was with only two animations and it was working just fine, when I added more animations I started getting this warning

Animator has not been initialized.
UnityEngine.Animator:SetFloat(String, Single)
PlayerControler:FixedUpdate() (at Assets/Skrypty/PlayerControler.cs:62)

I have not change anything in the animator (states) itself, but now none of the animations is working.
I have read that this bug was fixed in version 4.1. Do you have any idea how to fix it ?

EDIT//
I removed the animator and created new one with one simple animation and it is still not working.

Did you ever find the solution to this problem?? I am facing the same problem.
EDIT::
I just found the solution…I had mistakenly unchecked the animator component in the inspector pane
