This question is in reference to https://forums.adobe.com/message/6471520. I am having the same issue as MotionOw22 in this post. I need to use the Motion Editor for a class project and I have the newest version of the program. I can't get this feature to work after following the directions of the staff person in this post.
What is the problem you are facing? Are you not able to find the new Motion Editor or not able to work with it.?
Check the version of your Flash Pro (from Help > About Flash)
In Flash CC 2014, you first have to create a motion tween, then right click on the Motion Tween span in Timeline and click on 'Refine Tween'
I figured it out from reading another of your posts. Thanks for following up with me.
