iTween Path Editor

iTweens was updated last month and this method is not working anymore:

Can anyone attach the whole working package including the previous working iTween.cs file for this tutorial?

Do someone suggest another tool just for doing path translation animations and rotations?

Anyone have the whole package?

I downloaded it from the asset store. I have iTween.cs fut not iTweenPath.cs.
