Moving Directories – HELP

I built my site in a subdirectory (www/domain name/sub) and now I want to make it live (www/domain name). I moved all the files in my sub directory into my root folder but the old site is still showing. I used a purchased theme, but that shouldn’t matter, right?

And I changed the URI to “www/domain name” under the “Options” tab.

Am I missing something??
