This means the DB is still there and you can recover some data. You may open the DB to check if there is anything in it.
Before you start please export the DB — inside the phpMyAdmin toolbar you should see something like this, then you can export the entire DB to your computer. Also remember what is the DB name.
Then reinstall WordPress at your .com domain.
After the installation was complete, you’ll have to update your wp-config.php inside your .com htdocs folder.
Change only these lines:
// ** Database settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'The DB name' );
/** Database username */
define( 'DB_USER', 'Your hosting account username' );
/** Database password */
define( 'DB_PASSWORD', 'Your hosting account password' );
/** Database hostname */
define( 'DB_HOST', 'Your DB server' );
All of these data should be avaliable inside the client area. Please try the above steps and tell me if something went wrong.
