Problem 1
It's OK now with the new version. Thanks a lot !
Problem 2
I have found a solution...
I'm using the extension "Components Anywhere" from "Regular Labs" : 
www.regularlabs.com/extensions/componentsanywhere
1) Create a menu item with the "ARI Smart Book - Category" (If you don't want to see this menu item on your menu, for exemple 'mainmenu', you can create a another menu, for exemple 'menubooks' without module on it !
2) Copy the URL of the menu item, for exemple "index/fr/linkbooks" and create a module with these informations :
      * on the content of the module : 1 line '{component index/fr/linkbooks}'
      * on the position : exemple 'posbooks'
4) In your article
      * on the content : {loadposition posbooks}
For me it's OK...
