Login.aspx not redirecting using Forms authentication??? -- Same problem

HERE IS THE LOGIN ASPX CODE AFTER THE USER HAS BEEN AUTHENTICATED
 
FormsAuthentication.Initialize();
      FormsAuthentication.HashPasswordForStoringInConfigFile(edtPassword.Text,"md5");
      // Create a new ticket used for authentication
      FormsAuthenticationTicket Ticket = new FormsAuthenticationTicket(
                                             1,                           // Ticket version
                                             Convert.ToString(UserID),    // Username associated with ticket
                                             DateTime.Now,                // Date/time issued
                                             DateTime.Now.AddMinutes(30), // Date/time to expire
                                             true,                        // "true" for a persistent user cookie
                                             UserRole,                    // User-data, in this case the roles
                                             FormsAuthentication.FormsCookiePath);// Path cookie valid for
 
      // Encrypt the cookie using the machine key for secure transport
      string Hash = FormsAuthentication.Encrypt(Ticket);
      HttpCookie Cookie = new HttpCookie(FormsAuthentication.FormsCookieName, Hash);
      // Set the cookie's expiration time to the tickets expiration time
      if (Ticket.IsPersistent) Cookie.Expires = Ticket.Expiration;
      // Add the cookie to the list for outgoing response
      Response.Cookies.Add(Cookie);
      // Redirect to requested URL, or homepage if no previous page
      // requested
      //ReturnUrl = Request.QueryString["ReturnUrl"];
      string ReturnUrl="";      
      if (UserRole==c.RoleStudent)
        ReturnUrl = c.PageReportViewer;
      else
        ReturnUrl = c.PageMain;
        
      if (ReturnUrl == null) ReturnUrl = "/";
      // Don't call FormsAuthentication.RedirectFromLoginPage since it could replace the authentication ticket (cookie) we just added      
      Response.Redirect(ReturnUrl);
 
IN GLOBAL ASPX--------------------
void Application_AuthenticateRequest (Object sender, EventArgs e)
  {
    if (HttpContext.Current.User != null)
    {
        if (HttpContext.Current.User.Identity.IsAuthenticated)

                string UserData = Ticket.UserData;
                string[] Roles = UserData.Split(',');
                HttpContext.Current.User = new GenericPrincipal(ID,Roles);
