'flatten.txt' script for Acrobat 9 Flatten Document Menu Item

Hello,

I was following the steps in this blog (Add a Flatten Document Menu Item to Acrobat) to add a Flatten Document menu item in Acrobat 9, and the link the 'flatten.txt' script is dead.  The page directs you to this link:  https://acrobat.com/?d=KlVeiP4I1SXCRcTpRh-2wQ, which is just the Adobe Document Cloud webpage.  Does anybody have a copy of the 'flatten.txt' script?  I've used this before on my last computer, but since re-installing I have not been able to add this feature to Acrobat 9.  Any help is appreciated.  Thanks
