Thanks, did that. I just wanted to confirm that I didn't have to go through 3.236 on my way to 3.228,
The instructions X10 sent along with AHP and the CM15A said to install the software and not hook up the CM15a until prompted to. So, after loading 3.204 and upgrading to 3.228, I did not get the hook-up prompt. I had other things to do and finally got back to it last night. AHP seemed to open ok, but still no hook-up prompt. So I decided to just do it. I followed the directions in the User's guide: hooked up the USB cable, plugged the CM15a in and then installed the batteries. My PC then reported that it saw a new USB device and did I have the drivers for it?. I browsed a bunch and found nothing that looked relevant or worked.
By this time, I thought that my CM15a had 'locked up' and I had to reset it. I followed the instructions for that as posted in these forums, but that did not help so I turned around 3 times, thumped my chest, and howled at the moon. That didn't help either.
I uninstalled AHP and disconnected the CM15a. Then I loaded AHP 3.236 from the zip file X10 sent in the registration codes email. As I was installing 3.236, I received a notice that if I wanted to download the CM15a drivers 'click this button'.
Button clicked. Drivers downloaded. AHP 3.236 install successful. Lamp module test successful. Downgraded to 3.204. Upgraded to 3.228. Lamp module test successful. Looks like I'm in business. ...for some real fun.
