New Website Not Working

I am creating a new website, but am having a problem.

I registered a new new domain name with dreamhost, then made it fully hosted by them. I assumed that, like the first website I made, it would create a pre-made Dreamhost website. But it didn’t. I also tried to connect to the FTP using FileZilla but I couldn’t connect. It says
"Connection attempt failed with “EAI_NODATA - No address associated with nodename”."

How do I get the site up for me to start uploading?
