It a matter of making sure your local database and the remote database have the same tables.
and making sure that the Dreamweaver connection to the database is working.
First open the DW Database panel and test the connection to make sure the connection is working.
Then look at the local database and the remote database and make sure they have the same tables with the same structure.
if you need to recreate the tables on the local database, export the remote database, then import it to the local one.
We dont have a tutorial for this, but a google search of:
phpMyAdmin Import export
returns this one as the first result:
