[Solved] Problem with Html.Telerik().Menu() on release 2012.2.607

[Cesar]

I've updated my project to the new release 2012.2.607 in MVC and now my Html.Telerik().Menu() give a NullReferenceException when I click in some menu item. Did any one have an idea what can I do? 

@(Html.Telerik().Menu()
                    .Name("menu")
                    .Items(menu => {
                        menu.Add().Text("Inicio").Action("Index", "Home", new { area = ""});
                        menu.Add().Text(@PC.Admin.Resources.Menu.Administracion).Action("Index", "Home", new { area = "" }).Items(subitem =>
                        {
                            subitem.Add().Text(@PC.Admin.Resources.Menu.Administradores).Action("ListadoAdministradores", "Administradores", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.AccionesAnonimas).Action("AccionesAnonimas", "Acciones", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.AccionesAdministradores).Action("Acciones", "Acciones", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.AuditoriaAdministradores).Action("Auditoria", "Acciones", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.Roles).Action("Roles", "Roles", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.Procesos).Action("Procesos", "Procesos", new { area = "Administrador" });
                            subitem.Add().Text(@PC.Admin.Resources.Menu.ProcesosPorRol).Action("ProcesosPorRol", "ProcesosPorRol", new { area = "Administrador" });
                        });
                        menu.Add().Text(@PC.Admin.Resources.Menu.Clientes).Action("Index", "Home", new { area = "" }).Items(subitem =>
                        {
                            subitem.Add().Text(@PC.Admin.Resources.Menu.AutorizarRegistros).Action("AutorizarRegistros", "Registros", new { area = "Clientes" });
                        });
                        menu.Add().Text(@PC.Admin.Resources.Menu.Auditoria).Action("Index", "Home", new { area = "" }).Items(subitem =>
                        {
                            subitem.Add().Text(@PC.Admin.Resources.Menu.Errores).Action("AutorizarRegistros", "Registros", new { area = "Clientes" });
                        });
                    })
