Route not found with auth_generator

Hello I am quite new with rails and I am currently facing a problem
with a no route found to match ...
Here is the context :
- I have installed auth_generator to manage users & access
- when a user create an account or ask to reset his password, a mail
is sent with a link to click like the one below
http://cvouslechef.alwaysdata.net/account/confirm/xxxxx@free.fr,8f66c07c76814d214b3f01354d980da9e844bf07
- when the user clicks on this link he gets an application rails error
and the log contains a message
no route found to match account/confirm

The route.rb contains :
ActionController::Routing::Routes.draw do |map|
   map.connect '', :controller => "main"

# Route added for auth_generator plugin
   map.auth 'account/:action/:id',
      :controller => 'auth', :action => nil, :id => nil
   map.authadmin 'accountadmin/:action/:id',
      :controller => 'authadmin', :action => nil, :id => nil
  # end of Route added for auth_generator plugin
  map.connect ':controller/service.wsdl', :action => 'wsdl'

  # Install the default route as the lowest priority.
  map.connect ':controller/:action/:id.:format'
  map.connect ':controller/:action/:id'

end

There must be something with me because I looked at the

Sorry wrong manipulation.

I was saying that there must be something wrong with me, because I
looke at the auth_generator track and found no bug related to that and
apparently it is working for other people.

If you want to experience the problem you can go to http://cvouslechef.alwaysdata.net

I am using rails 1.2.6 and auth_generator 2.0.5

Thanks to give me some type to sort out this problem

Hello again

apparently looking at the log I can see that I have another route
error concerning also auth_generator :
no route found to match "/images/auth_generator/spinner.gif" with
{:method=>:get}

I don't know if this is related to the same issue but really any help
to find a solution would be very appreciated because this is
preventing me to kick off my site

Thanks again for your help

Nicolas
