Make sure you're using a stream copy on post rather than stream -> unicode string -> stream — user2009677

Here is the interesting part - NotFound is a very generic error, that can tell you that either the request failed internally or the web service rejected your request.

To get a better idea of what is going on, wrap it in a try/catch block (for a WebException) and read the response:

try
{
    HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(respResult);
    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        Debug.WriteLine(reader.ReadToEnd());
    }
}
catch (WebException ex)
{
    using (StreamReader reader = new StreamReader(ex.Response.GetResponseStream()))
    {
        Debug.WriteLine(reader.ReadToEnd());
    }
}

Report back with results and I will be able to help you more.
