Animator and Scripting problem

I'm not new to Unity, but this is the first time I tried to really jump into character animation. There are some weird behaviours that I consider bugs, but maybe it was my fault:
1. I have a layer for idle and smile. This works, but when I add a third layer no matter what animation I put in there it doesn't play.
2. I found this problem many times, but no solution, so I'm hoping it's been fixed by now:
If I want to play my blink clip using

Code (CSharp):

1. void blink()
2. {
3.      Animator myAnimator = GetComponent<Animator>();
4.      myAnimator.Play("Blink"); // error layer = -1...
5.      myAnimator.Play("Blink", 1) // I get the warning: Animator.GotoState: State could not be found
6. }

In both cases the animation does not play.

 

No idea about #1, but for #2 are you sure you have a state named "Blink" (capital B, with the exact same spelling)?

 

OK, that was a misunderstanding on my side. By dragging my animation clip into the Animator, it created a state
"Armature|Blink". I did not understand that each clip gets attached to a state and was really wondering why it didn't say "Clip not found". Thank you for assuming the worst.

 

As for the 1. Problem. I created a new FBX, since nothing was working any more, not even the entry animation. I was lucky I just started though, I'd hate let my Animator go down the tubes after I put work into them.
