downloading Steve Perry's noise reduction and web sharpening

I am working on a stand alone Photoshop CS6. I have not been updated since before the cloud was started. I downloaded Steve Perry's Web Sharpening and Noise reduction videos yesterday. When I extract a file I get a .ATN extension. When I click it , it opens in Photoshop and photoshop doesn't recognize it. I found actions under the window menu. When I click actions it opens the action Pallet. I cannot find anywhere the load actions tap. I see the downloaded file in the action pallet but nowhere to load them. Is my system too old to do this download? Where do I find load actions on my old system? Can I convert atn to mp4? I am running Win7 Pro 64 bit
Thanks for any help that might be coming.

Maybe this will help you:

Thanks for the info. Steve sent me Vimeo files instead of the atn. These worked really well. Now all I have to do is figure out smart objects and how to use them.
