Miss understanding (?) in Glossary configuration

Hello

I'm trying to install and use the glossary module, user to add some terms in the default glossary created under Taxonomy, but it doesn't seem to be active

http://www.edatis.com/dialog/support/glossaire/ => Page not found
http://www.edatis.com/dialog/support/glossaire/achat-d-espace => Is displaying the right description

Also, this page tells that there is no applicable glossary :
http://www.edatis.com/dialog/support/glossary/

In the installation & settings page, you say that when I enable the glossary filter for any input format, I will have to choose (on the same page) le glossary to use (from the list of Taxonomy created) I haven't this list to choose from

Any help ?

I thing I'm just missing a little detail about it all and that it should work well if the configuration is Ok

Thank you in advance
