well, your initial screen shot showed the files where not in the root of the Dreamweaver site, but in sub folders.
The files for power store or cms need to be at the root of the Dreamweaver site.
on each of the files that are based on the template will be a line like:
<!-- InstanceBegin template="/Templates/Main.dwt.php" codeOutsideHTMLIsLocked="false" -->
this is looking for the template folder at the root of the site. If the template folder is not at the root of the site, changes in the template will not be applied to the child pages.
