Hi,
Thank you for replying.
I re-ran to update with build option as suggested. The links on the homepage
now point to some local files (addresses). However, when I clicked, I got the
"OOPS...This page has not been retrieved by HTTrack Website Copier. Clic to
the link below to go to the online location!" 
Below is the log:

Is there any other option co select in order to tell HTTrack to retrieve the
new pages without copying the whole site again? (The current mirror is more
than a GB).
I don't quite understand your second statement.
Thanks & regards,
ib.
