Hello! Don’t worry, the action is absolutely correct and works perfectly with all Photoshop versions since CS3 up to CC2017 and CC2018. There are several possible reasons of your error:
First, please note: the action has two action modes (please see your Action panel) for different PS versions. You must use second version for your PS is CC2015, CC2017 or CC2018.
Second, please check you have installed the action brushes. If not, please drug Brushes filoe to your PS and try again.
Third, please check your new (not Background copy) layer name. It must be "profactions" (not "Profactions" or "Brush"). And with "profactions" layer selected, you must brush (use any color soft brush) your photo to choose areas for the effect.
Also, you can send me your PSD (and/or Photoshop screen when the action stopped at first) to email@example.com, so I can test your project.
