Problems Migrating to New Server

I have a WordPress site on a server that I want to move to a Yahoo Small Business server. I also want to change the url of this site. It’s not working. Here’s what I’ve done…

I backed up the current site into a desktop folder doing the following:
• Using the WordPress Database Backup plugin I made a copy of the database.
• Using Filezilla I copied the wp-content folder, the wp-config.php file, and the .htaccess file into this folder as well.

At Yahoo I used the one step install to create a new, virgin WordPress site.

Using phpMyAdmin I imported the current site database to the new WordPress site.
Using Filezilla I moved the current site wp-content folder and wp-config.php file to the new site. It would not let me move the .htaccess file.

When I try to access the site I get the ‘Error establishing a database connection’ message.

Does anyone have any suggestions, or have a website that deals with this topic? I didn’t delete anything from the new site – should I have? Should I create a new site on Yahoo without any WordPress files and move all the files and folders from the current site into this? Or is everything I’m doing wrong?

If I use dreamweaver to look at wp-config file I see something like what’s below (not real data). What do I need to change here? Thanks for any help!

/** The name of the database for WordPress */
define(‘DB_NAME’, ‘euirunbpy_wordpress6’);

/** MySQL database username */
define(‘DB_USER’, [redacted]);

/** MySQL database password */
define(‘DB_PASSWORD’, [redacted]);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);
