Can't connect to WebFTP / Filezilla question

I am trying to connect to WebFTP with the sub domain I just created to upload a wordpress theme and ecommerce plugin. I can’t seem to connect when I enter the username and password, I am getting this message:

Unable to connect to FTP server on port 21.

Are you sure this is the address of the FTP server? This is often different from that of the HTTP (web) server. Please contact your ISP helpdesk or system administrator for help.

Any ideas?

Also is it easier to work through FileZilla? And if so, how do I get it to connect with Dreamhost FTP?

Go to Manage Users in the panel and edit the user and see how it’s set up. Specifically is the “Disallow FTP” box checked?

Yes filezilla is a better choice. Setup:
