I've recently bought MultiView and Active Home Professional with iWitness. I downloaded the installation programs and installed them Tuesday evening. MultiView was a piece of cake. However, Active Home Pro wasn't.. it become a real pain. I'm praying that someone out there has experienced this and "fixed it". As I said, I downloaded the installation file, and then installed the applications. MultiView's icon appeared on my desktop, but there was nothing for AHP. So, I searched my computer, nothing. The AHP window was there asking for registration numbers. Being as I had put my printout of X10's email in a safe place, and had to remember where that safe place was, I gave up for the evening, shut my computer down. Wednesday after work, I went in (still no icon) and downloaded the AHP application again, enterred the registration numbers (now mind you the email doesn't say iWitness number is, and AHP number is, no it says: video and network) so I did eneny, meney, miney, mo, and put the -1 in for AHP and the -2 in for iWitness. The -2 worked, and it registerred. The -1 didn't. I called x10 and after I told her my story, a really nice gal told me to reboot. I did. When I logged in to my ISP, it told me that an application was using the com port and that I should close the application and try again. HELP!! There isn't any applications running in my computer that I can find. This has to be connected with the AHP install. Anyone out there have this problem? When I called x10 this morning, the tech said that she'd never heard of this before and would have to put the problem to a level 2 tech. Oh joy!!! I'd sure appreciate any help you have to offer. Thanks.
