Don't know if this pertains to your
situation, but I ordered the $49 plug in
upgrade w/ sensors. Received the package
without software or any activation email.
Contaced X10 support by phone, they sent
out an email along with registration code
(that corresponded to my plug-in order #)
and an attached 112KB file that I executed
once. It ran a download and installer, then
started up AHP program, which on startup
produced a 'plug in installed' message
prompting me to enter the plug-in
registration code. I did this and
received 'registration not found'. Called
support again, they told me to wait 5 hours
or possibly overnight since their system
showed the registration was pending. Tried
several more times last night, same result.
Note that if registration fails, you are
presented with 'cancel' and 'finish' options.
Cancel seemed to do nothing; finish cleared
the registration prompt window and allowed
regular use of the program. At that point
you could use the 'Plug In' menu bar option
to select a 'Register now' tab if you wanted
to retry the online registration.
Tried again this morning, this time
registration was accepted. Now if you try
to add a 'macro' with the plug in
successfully installed, you get a splash
screen with new conditional macro creation
options. Though I haven't done much other
than create a simple time-window conditional
macro, it's looking good so far.
