Hi:
Thanks for your relpy. I tried out with another site 
and HTTracks worked fine, so I tried the original site 
I wanted to download again and watched it out very 
carefully.

I realized HTTracks was working, but it starts 
downloading the other pages about 10 mins later. It 
seems HTTracks does a scanning of all the site first 
and then it starts to download the pages.

That's was completely new for me, because I used 
Teleport Pro and it starts to download the files 
inmediately. That's why I was confused, if HTTracks 
was working or not.
