Animation not working Unity 5

So I upgraded my project to unity 5 but now ALL animations on the project just don’t work !!!
whats the problem

Every thing was working fine before upgrading to unity 5

My issue was with the “Apply root motion” tick box. Also, make sure that the animated objects don’t have a tick in the “Batching Static” tick box.

Same issue. Instead of removing I just reset the component and worked again fine.

I ended up having to replace all of my Animator components.

I had the same issue on some of my animations. Removing and re-adding the animator fixed the problem.

I ended up having to delete my whole project. That and none of the scripts work anymore. I tried to change them to “the current C#” requirements and it all comes back with errors. And the so called “suggestions” that it gives don’t work worth squat.
