Populating xml using c# error

I am populating an xml document using c#. If I populate it once then everything is ok but when I try to repopulate it a second time (without closing the program) I get an error message and rubish gets written to the bottom of the xml file.

I'm sure I've found the answer to this question before but I can't find it.

I'm sure its something to do with the fact that I'm not closing something down after updating the xml document or something but I can't remember what exactly I have to close down.

Sorry I hope you all understand. I find it difficult to explain.

Code:

using (FileStream READER = new FileStream(fpath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
      {
                System.Xml.XmlDocument Template = new System.Xml.XmlDocument();// Set up the XmlDocument //
                Template.Load(READER); //Load the data from the file into the XmlDocument //

                //**********Grab nodes to be written to********


                using (FileStream WRITER = new FileStream(fpath, FileMode.Open, FileAccess.Write, FileShare.ReadWrite))
                {
                    //Set up the filestream (READER) //
                    //Write the data to the filestream
                    Template.Save(WRITER);

You read and write in the same file fpath

You have to close the reader after Template.Load(READER);

  using (FileStream READER = new FileStream(fpath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
  {
       System.Xml.XmlDocument Template = new System.Xml.XmlDocument();// Set up the XmlDocument //
       Template.Load(READER); //Load the data from the file into the XmlDocument //
  }

  //**********Grab nodes to be written to********


  using (FileStream WRITER = new FileStream(fpath, FileMode.Open, FileAccess.Write, FileShare.ReadWrite))
  {
     //Set up the filestream (READER) //
     //Write the data to the filestream
     Template.Save(WRITER);
     ...
  }
