Not sure if you've done this already, but if you understand the animation controller a bit, try writing out on paper how the animation controller should work to a T, then make sure it conforms exactly to that in the editor. You can check off each aspect of it specifically as you go through it.
I just read your posts and if you're only changing a sprite, it might be easier to do that in code within your character / input controller

not sure if cgcookie's articles are behind a paywall, but I recommend their service for someone willi ng to pay for education. I'm not an expert but I'm comfortable working with it now after their lil course on the animation controller. I don't know of any non-video guides off the top of my head sadly :/
What exactly do you want to happen to your character through using the animation controller?
I need to set up idling and jumping loops, plus a fishing casting animation when a certain condition is met, which I'll probably use through a true/false variable.
I checked CGCookie pricing but $30 is a bit out of my price range right now. :.) I usually use Udemy when I can.
