Photographic Edges issue

I'm not satisfied yet with answers from Auto FX Software about how Photographic Edges 6.0 isn't working with my Photoshop CS3. Seems to me there should be a new plugin. The only one on the CD, file name PGE_PlugIn.8bf, dates back to OS 9. When I run PGE as a stand-alone app. and save a TIFF file created with it, Photoshop won't recognize it. Can anyone shed some light on this for me?
