I setup RoR and now I'm trying to setup Act As Authenticated to run on it. I installed it, and it works fine; however, when I add "include AuthenticatedSystem" to application.rb I get an error page:

undefined method `helper_method' for Object:Class
RAILS_ROOT: /home/applications/mysite/config/..
#{RAILS_ROOT}/lib/authenticated_system.rb:96:in `send'
#{RAILS_ROOT}/lib/authenticated_system.rb:96:in `included'

Is my RAILS_ROOT set to the wrong directory? If so, how can I change it?
