CS4 Spry field validation - CS3 files?

Question

I designed a form in CS3.  I am now working in CS4 so I was getting a Spry error message - about outdated code.  I reentered all the validation fields but now the error messages show in the form when it is launched.  I realized my Spry folder of files is the original ones from CS3.  How do I get the new files I need?  I have run this through the validator and fixed everything I know how to fix - even though that isn't all of it!
files are http://streitenterprises.fatcow.com/contact/index.html

Thanks, I actually found that article earlier and it also reads: 
"This extension updates Dreamweaver CS3 to use the Spry 1.6.1 assets for its current features. The extension also updates code hinting and code coloring to reflect the latest updates in Spry 1.6.1. The Spry Updater includes a command that provides the ability to update the Spry assets in your site(s). This extension only updates existing Spry files in Dreamweaver CS3 and those used in your sites. It does not add any additional functionality (widgets, etc) to the product."
I updated to version 1.6.1 long ago.  The updater only applies to built-in CS3 widgets - it doesn't ADD new widgets that have come out since CS3 (unless I'm completely missing something here).  What I'm looking for is to add widgets that I don't have in CS3, kinda like adding extensions.  Am thinking one must purchase CS4 to get the four additional widgets it provides?
"CS4 also adds four new Spry wizards to 13 available in CS3. These are the Spry Validation Password, Spry Validation Confirm, Spry Validation Radio Control Group, and Spry Tooltip."
I'm want those without having to upgrade to CS4!
