I have downloaded a site (talk.hyperreal.info). I get a lot of files (~3gb) but
its not full site, some links are 404 (like
talk_hyperreal/talk.hyperreal.info/najlepsze-motywy-303-t31193.html - not
working, but
<http://192.168.1.3/~mirrory%20stron/talk_hyperreal/talk.hyperreal.info/doc-t17072.html>
is working, its randomly 404 :/). 

Site need log-in, but i don't have problem with it - it works. Only problem is
not downloaded 1/3 of pages or more. What is the problem?
