hi,

I am a newbie to flex and I get the following error when trying to run the sample example using Web application to launch. Is that url still valid?

[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error.
