I have been having the same problem as the other people in this thread--Ad-Watch fails to load or work in my new copy of Ad-Aware 2007 Plus. I've written customer support twice, and gotten unhelpful replies. Why did Lavasoft create a new version of its software that is not compatible with Vista, considering Vista has been out for many months now? I only upgraded to A-A 2007 Plus because every time I loaded the old Ad-Aware SE, I would receive messages saying it was imperative that I upgrade now.
