As Dave pointed out. There are no free downloads for the plug ins. X10 emails you a download link for each piece of software in the order.
That link gets you a loader program not the whole thing. The loader program install the whole program from X10's Servers.
Where did you buy the package?
If it was X10.com did you use the main display page or the "What's On Sale" tab near the top of the screen.
Packages vary depending on where you look. Some include the plug ins some do not.
In fact there is one on the original sales page {not the new one} that is called the Green Automation Package. AHP, CM15A, all the plug ins and an Appliance Module.
On the X10.com web page near the bottom of the screen. 'Go to the Original X10 Homepage' Link gets you there. Nice lady pushing the Newsletter and all.
