Object reference not set to an instance of an object.

har et asp.net projekt hvor der er indsat en ocx kontrol i
jeg har så refereret til den via interop men når jeg prøver at hive fat i den får jeg den her fejl:

Object reference not set to an instance of an object.

stacktrace:

Line 54: string netbase = xpoint.BasePath;

koden kommer her:

        protected System.Web.UI.WebControls.DropDownList yearDrop;
        protected System.Web.UI.WebControls.Label lblDesc;
        protected System.Web.UI.WebControls.Label lblName;
        protected System.Web.UI.HtmlControls.HtmlForm dstForm;
        protected System.Web.UI.WebControls.Label lblYear;
        protected PowerXLib.PowerX xpoint;


public void GetStatsAndFill(long dstid)
        {
            string ConnStr = System.Configuration.ConfigurationSettings.AppSettings.Get("connStr");
            MySqlConnection Conn = new MySqlConnection(ConnStr);
            Conn.Open();

            string SelectStr =  "SELECT statid,name,description,file,dstid,year FROM statistik WHERE dstid = '"+dstid+"' ORDER BY statid DESC";
            MySqlDataAdapter statAdapter = new MySqlDataAdapter(SelectStr, ConnStr);
            DataSet statSet = new DataSet();
            statAdapter.Fill(statSet, "statistik");
            Conn.Close();

            yearDrop.DataSource = statSet.Tables[0];
            yearDrop.DataValueField = "statid";
            yearDrop.DataTextField = "year";
            yearDrop.DataBind();

            lblName.Text = statSet.Tables[0].Rows[0].ItemArray[1].ToString();
            lblDesc.Text = statSet.Tables[0].Rows[0].ItemArray[2].ToString();

            string netbase = xpoint.BasePath;
            xpoint.ArchiveURL = "/data/xpa/"+statSet.Tables[0].Rows[0].ItemArray[3].ToString();
            xpoint.ReadConfig();
