OK, then RSP is up and running, so that’s not the issue.
Do you get to the FirePlay interface at all, or is it just a blank page?
Do you get a password dialog when browsing to “http://server:9999/FirePlay.html”?
You say that you’re connected to “http://server:9999” is this in the browser address bar or in the FirePlay interface? In FirePlay it should say “Connected to Firefly Media Server” in your case.
