Watercolor artists - perfectum 2- photoshop action, EROR

Hi I am just both watercolor artists - perfectum 2- photoshop action.
The action does not work for a moment.
There is a message for the missing select button. Also I have a message that layer 4 is not currently available. I sent a email also to profactions@gmail.com but I did not have any answer jet.

Can you please guide me what to do?

Thank you.
