Hello Every 1. I have a strange problem with webclient. I have the following method in a class created to download files from a website. I download files sequentially i.e download one file dispose the download class object then create a new object and call the download method and so on....

public void DownloadVideo()
        {          
            try
            {
                ///The WebClient object that will download the file
                WebClient wcDownload = new WebClient();
                // Create a request to the file we are downloading
                webRequest = (HttpWebRequest)WebRequest.Create(_VideoUrl);
                // Set default authentication for retrieving the file
                webRequest.Credentials = CredentialCache.DefaultCredentials;
                // Retrieve the response from the server
                webResponse = (HttpWebResponse)webRequest.GetResponse();
                //check if the webresponse is ok
                if (webResponse.ResponseUri.ToString() != "http://www.xyz.com/error.htm")
                {
                    // Ask the server for the file size and store it
                    Int64 fileSize = webResponse.ContentLength;
                    // Open the URL for download             
                    strResponse = wcDownload.OpenRead(_VideoUrl);
                    // Create a new local file stream 
                    strLocal = new FileStream(_VideoPath, FileMode.Create, FileAccess.Write, FileShare.None);
                    // It will store the current number of bytes we retrieved from the server
                    int bytesSize = 0;
                    // A buffer for storing and writing the data retrieved from the server
                    byte[] downBuffer = new byte[2048];
                    // Loop through the buffer until the buffer is empty
                    while ((bytesSize = strResponse.Read(downBuffer, 0, downBuffer.Length)) > 0)
                    {
                        // Write the data from the buffer to the local hard drive
                        strLocal.Write(downBuffer, 0, bytesSize);
                        UpdateVideoProgressEventArgs uvpea = new UpdateVideoProgressEventArgs(strLocal.Length, fileSize);
                        UpdateVideoProgressEvent(this, uvpea);
                    }
                }//end of second if
            }//end of try
            catch (Exception exp)
            {
                MessageBox.Show("Error in startDownload due to : " + exp.Mess
