Can't get this module to work

Hello,
I followed the README but i can't get this module working =(
i have:
-installed chamilo
-insert new variables in the Chamilo main.settings_current table
-insert new variables in the Chamilo main.settings_options table
-configure the SSO module in chamilo :
-Single Sign On "YES"
-Domain Single Sign On "localhost/mysite"
-URL auth "/?q=user"
-protocole "http://"
-configure the chamilo module in drupal :
-SSO Server Protocol : "http://"
-Application URL and Path : www.chamilo-mysite.com
-user name : "admin" (i dont know which user name i need to provide, drupal admin , chamilo admin ???)
-key : which in the configuration.php

When i go to my admin profile i see nothing in the "chamilo setting" , only the "save" button.

Chamilo blocks display nothing, and "Chamilo trainings block" give me this error :
SoapFault : Function ("DokeosWSCourseList") is not a valid method for this service dans SoapClient->__call() (ligne 396 dans C:\Program Files\wamp\www\mysite\sites\all\modules\chamilo\chamilo.module).

Any helps? Should i miss something? i need to install a "Single sign on" module ?

ty

PS: i use the dev version and use the last chamilo release 1.8.8 (6 may)
