Have you gone back to double check your connection setting to make sure that everything is as it should be?

Are you on a windows hosting plan?

Currently the windows hosting plans do not support remote connections to database.

If you are on a linux hosting plan, from withing the MySQL Account Maintenance   area, you will want to verify that you have in the Access Hosts section:

%
and
localhost

Also, you may need to place in your ip address (www.whatismyip.com)

If none of these work, submit a ticket to support@lunarpages.com providing the following information:

Primary domain name:
Database name:
Database username:
Database password:

And make sure to mention you are using dreamweaver.
