XML for Pocket PC on Windows CE Platform

Hello, I am trying to convert my C# application to work on a Pocket PC using Windows CE platforms. I have got the Windows WM Developer Resource Kit installed.
The problem is that it keeps on saying that the XML file is not found. does anyone know what is wrong with the below code.

Code:

---

public static string doRead()
        {

            reader = new XmlTextReader("users.xml");
                while (reader.Read())
                {
                    //This will move to the Next Record
                    contents = null;
                    reader.MoveToContent();
                    //This If statement will only allow the Text within a Tag to be accessed
                    if (reader.NodeType == System.Xml.XmlNodeType.Text)
                    {

                        contents = encryption.Decrypt(reader.Value);
                        return contents;

                    }


                }
                finish = "True";
                ic = 0;
                reader.Close();
                return contents = null;
}
