I went back through my files and found a FAQ for her scripts and this is what it said
If you get this error message it is because the script file, jsx file, has been copied to the wrong location or is in the right location but somehow got renamed. The action and png files are correct, but the jsx file location must be corrected. Double check the path where the jsx file needs to be put. If this is the first script you are installing, there will not be any other files in the folder where the script goes, only other folders.
Hope this helps!!
