I've tried this a lot over past few days with different versions of things.  I am using 12.1 and I get:
Error 8800  The functionality may not be available in this version of Photoshop.  The command <unknown>  is not available.
Line 1089 
Execute action  (perfectumonezerozero,desc3, dialoguemodes.no);
I take it this means my version of perfectum (v2+) HAS to be 1.4?  Can anyone edit the script for me to remove perfectum completely?  I don't even want to use it!
edit:  yeah it is that.  I don't like that smoother (it makes the backgrounds look plastic and fake), so if anyone will remove it from script for me, I would be very grateful.
edit 2, I just removed the sections between { and } and that seems to have done the trick.  Why anyone would use that grain or smoother is beyond me.  Other than that Facepalmer is great
