Photoshop: The area is empty or does not overlap with the workspace

Hello, 
I have done this many times, but now when i record an action (cropping an saving an image) and want to use it for many other files the same way, it shows me this message:

"The command could not be completed because the area is empty or does not overlap with the workspace."

The files are PNG and all the same size. Do you know what's wrong? i even installed the old version of PS but it still shows me this message. Is there a checkbox a forgot?

thank you for your help. 

cheers
