I'm not sure, but there are a couple of things in the instructions that you may want to check:
Before you run the action -
1. Are you starting with a photo/image that is named 'Background' in you layers panel?
2. Are you sure your foreground color is set to black and your background color is set to white?
There's also a video tutorial that Syndee included with her instructions. Maybe that will help?
If all else fails, Syndee included her email address in the instructions or you could send her a PM. Hope you can get it to work...
I just thought of something else - before you ran the action did you check to be sure the pattern file is the current active pattern in the Preset Manager?
See steps 1-4 here: Post #11
In step 2 you want to select 'SNU_SSActions_ArtisticPhotoMasks6301-PATTERNS' from the menu. HTH!
