How to work with an EXISTING wordpress site in side DW CS5 (yahoo hosted)

Question

Have and existing  Wordpress site that is hosted by Yahoo.  Recently upgraded to  Dreamweaver CS5. Was really excited about working with my Wordpress  files inside of DW CS5 with all of it's new capabilities, bells and  wistles.  I can't seem to get it set up right.
Is Dreamweaver CS5 ABLE to display existing wordpress sites with dynamic content? And can anyone please help me figure out how.
I have been thru several lynda.com video tutorials including:
Dreamweaver CS5 and Wordpress 3 by Joseph Lowery (over the last month)
Dreamweaver CS5 with PHP and MySQL by David Gassner (over the last month)
PHP with MySQL essetial training by Kevin Skoglund (about a year ago when trying to learn php)
Self-hosting a Wordpress site (about a year ago when I set up the site)
I have also been scouring this forum and the web trying to find the answer to what seems to be a very common problem.
Using Mac OSX 10.6.6
MAMP
Dreamweaver CS5
Wordpress 3
Yahoo web hosting
Everything works fine with the exercise files but as soon as I try my existing site files it gives me one of several errors
     cannot establish a connection to the database
I set up my site thur the DW site manager with the
Local Site Folder set to: /applications/MAMP/htdocs/nate
server set to:
name: testing
connection using: local/network
server folder:  /applications/MAMP/htdocs/nate
web url: http://localhost/nate
under the advanced tab i have set the server model to: php mysql
and have the testing box checked in the site set up dialog box
I also set a remote server:
name: remote
connect using: ftp
ftp address: ftp.MY_SITE_NAME.com
username: myusername@MY_SITE_NAME.com
password:  mypassword
under the advanced tab i have the server model set to: php mysql
and have the remote box checked in the site set up dialog box
when tested connection was made.  I also downloaded all of my site files using this connections (it took hours).
I installed MAMP and set the ports to the defauls (80, 3306) host: localhost username: root password: root
If i change the database settings in the wordpress wp-config.php file  to: localhost, root, root it works and displays my page as I would  expect in live view or browser but without the main content area or  posts - displays a 404 error where the content should beI have exported my wp database and imported back into my local testing server thru phpmyadmin.
I have also gotten this error at various tries in the set ups: "dynamically-related files could not be resolved because of an internal server error"
I am currently getting this error: "Dynamically related files could not be resolved because the site definition is not correct for this server"
It is not asking me if I want to save files to the server when I hit live view.
Everything  works fine with the lynda.com exercise files and with the generic wordpress files.  I can open any page -  live view or view in browser  - can access and modify the imported  database thur dreamweaver and phpmyadmin. I am only having these problems with my existing site files. I have done the complete set up at least 5 times from scratch going thru the videos and various tutorials step by step.  I dont want to use the starter files that come with wordpress installations I want to use my highly modified pages/themes/database

DW does not work with a WP installation that has anything other than the default (numeric) permalinks. Apparently no-one ever tested this case during the development and prerelease phase, which is a shame, because very few WP installations use default permalinks. It's a point that Joseph Lowery doesn't touch in his tutorial, and of course the tutorial WP installation works perfectly.
Hope that helps, although it may disappoint (as it did me, and a lot of other folks). Here's hoping this is addressed in a dot release.
