flash remoting netConnection debugger error

[cochise]

I'm trying to connect to Amazon's web service; however, I get the following error in my netConnection debugger:

DebugId: 0
EventType: "Result"
MovieUrl: "file:///C|/PathToFlashFile.swf
Source: "Client"
Time: 1121048284141
Date (object #1)
....."Sun Jul 10 22:18:04 GMT-0400 2005"
Result (object #2)
.....detail: "The request contains an invalid SOAP body."
.....faultcode: "SOAP-ENV:Client"
.....faultstring: "We encountered an error at our end while processing your request. Please try again
"

Does anyone know the cause, and if so the solution?
