controller missing - locale

Hi all, I am having a problem at the moment with my code in which if I
incase my routes with scope '(:locale)' do buy I get the error
controller missing, any ideas why?

Games::Application.routes.draw do

scope '(:locale)' do
  get "game_interest/new"
  get "rules/index"
  get "feedback/index"
  get "help/index"

  get "log_in" => "sessions#new", :as => "log_in"
  get "log_out" => "sessions#destroy", :as => "log_out"
  get "sign_up" => "users#new", :as => "sign_up"

  get "home/index"
  get "about/index"

  resources :feedbacks
  resources :password_resets
  resources :contact_messages
  resources :wishlists
  resources :searches
  resources :help
  resources :users
  resources :sessions

  resources :games do
    post 'email', :on => :member
    post 'gensearch', :on => :member
    post 'consearch', :on => :member
  end

  root :to => 'home#index'
end
end

I have the following in my application_controller

  before_filter :set_i18n_locale_from_params

  def set_i18n_locale_from_params
    if params[:locale]
      if I18n.available_locales.include?(params[:locale].to_sym)
      I18n.locale = params[:locale]
      else
      flash.now[:notice] =
      "#{params[:locale]} translation not available"
      logger.error flash.now[:notice]
      end
    end
  end

  def default_url_options
    { :locale => I18n.locale }
  end

Can you paste the exact error that you are getting?

No worries, solved.
