FTPwebresponse protocol violation error.

I have the following function which worked fine.  Basically its an ftp  upload function for a C# GUI to upload mp3s to a server.  However it throws a weird error now when I try to connect to ftp.
"The underlying connection was closed: The server committed a protocol violation."

Here is the code.  Anybody have any idea on what is wrong?
FTP login info is
host=mydgbc.org
username=test@desertgatewaybaptist.org
password=testtest

and here is my c# code
[code]
private void Upload(string filename)
        {
            FileInfo fileInf = new FileInfo(filename);
            string uri = "ftp://" + ftpServerIP + "/" + fileInf.Name;
            FtpWebRequest reqFTP;

            // Create FtpWebRequest object from the Uri provided
            reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + fileInf.Name));
            // Provide the WebPermission Credintials
            reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);

            // By default KeepAlive is true, where the control connection is not closed
            // after a command is executed.
            reqFTP.KeepAlive = false;

            // Specify the command to be executed.
            reqFTP.Method = WebRequestMethods.Ftp.UploadFile;

            // Specify the data transfer type.
            reqFTP.UseBinary = true;

            // Notify the server about the size of the uploaded file
            reqFTP.ContentLength = fileInf.Length;

            // The buffer size is set to 2kb
            int buffLength = 2048;
            byte[] buff = new byte[buffLength];
            int contentLen;

            // Opens a file stream (System.IO.FileStream) to read the file to be uploaded
            FileStream fs = fileInf.OpenRead();
            try
            {
                // Stream to which the file to be upload is written
                Stream strm = reqFTP.GetRequestStream();

                // Read from the file stream 2kb at a time
                contentLen = fs.Read(buff, 0, buffLength);

                // Till Stream content ends
                while (contentLen != 0)
                {
                    // Write Content from the file stream to the FTP Upload Stream
                    strm.Write(buff, 0, contentLen);
                    contentLen = fs.Read(buff, 0, buffLength);
                }

                // Close the file stream and the Request Stream
                strm.Close();
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                //MessageBox.Show(response.BannerMessage);
                MessageBox.Show(response.StatusDescription);
                fs.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Upload Error");
            }
        }
