Red5 demos failing to run

Question

I am running Red5 1.0.7 on Windows 8. I am abke to start the server, but when I attempt to run a SimpleChat demo (http://localhost:5080/demos/SimpleChat.html) I get the following failure:

[WARN] [RTMPConnectionExecutor-1] org.red5.server.net.rtmp.RTMPHandler - Scope not found

In fact, I get similar errors when I attempt to run any demo application. For example, with the Bandwidth Check application (http://localhost:5080/demos/bwcheck.html):

[WARN] [RTMPConnectionExecutor-2] org.red5.server.net.rtmp.RTMPHandler - Scope not found

I had thought that there probably was a need to actually install these applications, so I tried running the installer (http://localhost:5080/installer/). When I start that, however, I don't see any applications in the list and on the server side I am getting the following:

[INFO] [RTMPConnectionExecutor-3] org.red5.server.adapter.ApplicationAdapter - W3C x-category:session x-event:connect c-ip:0:0:0:0:0:0:0:1 c-client-id:0
[WARN] [RTMPConnectionExecutor-4] org.red5.server.service.Installer - Service returned an error

There is clearly some kind of configuration or installation problem, but I cannot find it. Does anyone know what is causing these problems and how to fix them?

Please advise.
