Problem to add PlayMaker to a existing project

[Gino]

Hello! I'm new at this. I am trying to add PlayMaker to my project, Once downloaded does not appear in the top menu and get me this message in the console when a try to hit the play button: Assets/PlayMaker/Actions/EnableAnimation.cs(54,25): error CS0029: Cannot implicitly convert type `UnityEngine.AnimationState` to `AnimationState´

and appears many messages like this

What can be?  Thanks!

Hi,

 What scene are you playing?

Probably a script in your project has defined a class called AnimationState, conflicting with UnityEngine.AnimationState. You should rename that class to avoid the conflict.
