Topic: Getting Act as Authenticated to work

I have a new project, basically I started with installing Act as Authenticated, and I have not done anything except these things below at the moment.

I have run:

script/generate authenticated user account
rake db:migrate

Next I ran:

script/generate authenticated_mailer user
rake db:migrate

I also ran:
script\plugin install annotate_models
rake annotate_models

No error messages!

When I start my mongrel server in InstantRails I get the startpage (default Welcome Aboard).

If I enter:

http://localhost:3000/account/index

I get redirected to ../account/signup and can enter login etc.

When I press submit, I get errors:

NoMethodError in AccountController#signup

undefined method `current_user=' for #<AccountController:0x496c2fc>

RAILS_ROOT: E:/INSTAN~1/rails_apps/member/config/..
Application Trace | Framework Trace | Full Trace

#{RAILS_ROOT}/app/controllers/account_controller.rb:29:in `signup'

Anyone got any ideas? I am new to working with RoR, so it might be basic

Thanks!
