Error trying to export

Question

I'm trying to export files from LR3 onto my hard disc (as normal).  I've just got the following message.  Would really appreciate some help:
internal error ?:0 attempt to index a nil value
Thanks,
Steve

Hi Rogerio,
your URL looks fine.  I think the issue is with the Body where you have text in-line with the binary content of the file.
To get it working for myself, I broke the body into 3 parts, the header, the file stream and the footer.
I converted the header and footer into byte arrays and then concatenated the 3 parts together as my request stream.
the below is C# code, but hopefully it demonstrates what I'm talking about:
               //write the request body to the stream
                byte[] reqBodyStart = System.Text.Encoding.UTF8.GetBytes(bodyStart);
                byte[] reqBodyEnd = System.Text.Encoding.UTF8.GetBytes(bodyEnd);
                Stream reqStream = myWebRequest.GetRequestStream();
                reqStream.Write(reqBodyStart, 0, reqBodyStart.Length);
                //add file to stream
                reqStream.Write(filestream, 0, filestream.Length);
                reqStream.Write(reqBodyEnd, 0, reqBodyEnd.Length);
                reqStream.Close();
