Note that some folders won't be downloaded by default, 
because of robots.txt rules:

17:46:58 Info:  Note: due to www.bnf.org remote robots.txt 
rules, links begining with these path will be 
forbidden: /navButtons, /navSecondMenu, /templates, /Library
, /images, /scripts (see in the options to disable this)

If you still have troubles, try to use the 3.30 pre-
release ; some problems were reported with "bad keep-alive" 
sites.

As far as I can see (115 links downloaded yet), this site 
seems to be okay with 3.30RC1.
