Red5 404 error

hi everyone.

I just installed OpenFire and install Red5 plugin but when i try to access http://host:port/red5/index.html the server says Error 404 (as you can see at the attachment). The HTTP Binding it's activate.

I change the default HTTP Binding port because when I click on Video Rooster on Spark->Red5 its says that port.

The server it's on a CentOS 5.0 Server and the clients are Windows XP Spark.

Sry about my english.
