Thank you so much for using our theme and thanks for your questions too. We only provide access to the premium theme support for our premium users. We know that you have a better knowledge about WordPress codes and child themes.
While editing the parent theme from child theme, you have to make the folder structure same as parent theme on the child theme.
1. Create a child theme. (You already have it)
2. Make the same directory path as parent theme on child theme.
Example: If you want to edit the file which is inside the
acmethemes/hook/header.php make the same directory path on child theme.
acmethemes/hook/header.php No need to add the the files inside the directory, just put the file which you are going to edit.
3. If you need to edit some other files, please follow the same process on 2.
