New user and new install... getting Failed to load FLV: rtmp://[URL]

Ok, I'm stumped. I have been fighting with this thing for days on end and working into the night... but I cannot get Flash Media Server to work.

I would love to call tech support, but they won't help because I don't own the software... but the guys who pay the bills around here won't let me buy the software until I demo this thing for them.

Here is what is happening:

I have installed FMS on a Windows Server 2003 box and used all of the default settings.

I created a "sample" folder under the applications folder. I also added a _defInst_ folder:
C:\Program Files\Macromedia\Flash Media Server 2\applications\sample\_defInst_

I then went to Flash 8 and created a test Flash Document and attempted to import the flv video file... however I get the following error:
================================================
Failed to load FLV: rtmp://[IPAddress]/sample/sample.flv
================================================

I can watch the "sample" application in the Admin Console and observe that the "sample" appliction is in fact being connected to, but no thing happens beyond that and then I get the error.


What am I missing?
Is there some sort of client authentication I need to do?
Do I need to setup a user account on the server?

I'm not trying to do anything fancy... I just want a video to play from the server. Nothing else.

I'm extremely disappointed that Adobe did not provide a sample with the FMS install.

Please Help!
