FLV path to subfolder not working

I've set up FMS Streaming Server 3.0 on one of my servers.

I've created the Adapter, Host and Application, pointed the <Streams>/;D:\Flash Media Server 3\applications\2368\media</Streams> correctly, and I am able to successfuly connect to a FLV using the built-in FLVPlayback component with this path:

rtmp://mydomainname.com:1935/2368/FlashMovie.flv

Everythis worked fine.

Now, I then created a sub-folder inside the media folder and put another movie there. The physicial file path is:

D:\Flash Media Server 3\applications\2368\media\videovault\FlashMovie.flv

But this rtmp path cannot connect.

rtmp://mydomainname.com:1935/2368/videovault/FlashMovie.flv

I get this error:

Error #2044: Unhandled NetStatusEvent:. level=error, code=NetStream.Play.StreamNotFound

Does anyone know why this might be?
