BookLibary Component Support

I've just buy a pro version of Booklibrary.
I've export my old base with full xml export.
I installed the new version of BookLibrary after desinstall the ancient.
All works except z39.50 protocol.
I imported the database (Full XML)
In the backend, I show all books and categories.
in the frontend... nothing ! !
If i create a new new category and a new book in this category I show the book...
One idea ?
Thanks in advance.

Sorry for my english, I'm french

I think I found the solution.
After import, I need to check every category and put acces rights to Everyone...
It seems to work.
