Happy to help. Here are the settings you'll want to use:
Password: Your root password
Host/Server: Your droplet's IP address
On a newly created droplet you will not be able to make an SFTP connection until you log in via ssh or the console in the control panel. On the first login you are prompted to create a new root password to replace the temporary one that was emailed to you. After logging in this will first prompt you to enter your current password a second time and then will request that you enter a new password twice. Once you've replaced your temporary password your droplet will accept SFTP connections.
