I got it working!

For some reason, I have two sets of instructions. The readme file that came with Hidden Power Tools Action player, and a document by Richard that I pulled from the web somewhere. I don't know if the latter document is just a different method or what....but I couldn't get the action installed with that method. Here are the two methods. Was I trying to do something completely meant to do something else?
Method that didn't work:
installed action player
created preview image and named it underwater.psd
copied underwater.psd and underwater.atn into a folder I named underwater,
and placed that folder into the Previews\Effects folder.
deleted cache, emptied wastebasket and restarted Elements.
Method that did work:
copied underwater.atn file into the Presets\PhotoshopActions folder
Edited the index.html file in the Welcome\PhotoFixes folder
Inserted the HTML code for the underwater action per Richards instructions
that I found in this forum
deleted cache, emptied wastebasket and restarted Elements
So, was the first method meant to do something else? VERY HAPPY that I got it working!!
Thanks!!
