I've installed a theme but my site won't display

I have a new domain and I've just installed WPD. I installed a theme but when I look at my site I still see the Index Of displayed. Can anyone help?

Theme Installed But Still Showing Index Of Page

After a long fight with the WPD FTP login I finally got it to connect. It goes through all the install with no errors but when I go back to my site all I see is the "index of" page. I can see that it has uploaded some files. empty.php
