Yes, thanks. Couple of things to check. First, in AHP, click on "Help" and then "Check For Updates". Downloads are free so go ahead with the update if you need one.
Second, again in AHP, click on "MyHouse" and then "Connect To MyHouse Service" before you try to access from a remote computer. Needless to say you should leave your copy of AHP running. By the way this turns off whenever you exit AHP so you have to do it each time you want remote access, unless you leave it on all the time with "Connect On Program Startup". I'm not comfortable with that option though.
I'm assuming you've already defined a remote user with name and password in "User Configuration".
