DW Templates issue with PowerCMS Builder

I installed PowerCMS Builder and got it activated (after some technical help - thanks, Jason).

I opened up one of the sites I was working on and modified a Dreamweaver template that I was using for all the pages of the site.

I found that the changes did not propagate correctly. I then found that in fact some of the pages had been detached from the template I had created. I believe these were pages that I had opened and contained PHP includes from PowerCMS Builder.

PowerCMS Builder installed a number of templates in my site, and I'm not sure what effect that might have had on my original site template.

I know I did not detach these pages (intentionally) from their template. My question - is it possible that PowerCMS Builder could somehow detach a page from its template when that page is open in DW, with a connection to the server?

As a second question, let's imagine that I'm finding the PowerCMS Builder extension more trouble than it's worth. But I still want to use and install PowerCMS (which I'm very happy with). I assume that I can legally do this, and that all of the PowerCMS files are included in the Builder extension.

Can you tell me where I find these files? Can they be uploaded and activated in the same way they were with PowerCMS? Does my activation code for the extension work as the activation code for PowerCMS?

Thanks....Duane
