Mr Roche, thank you for your response.

Unfortunately, I'm not sure what you mean by "proxy 
hostname".  Is this the same as the proxy server address?
If I go through a proxy server, I'll enter the address # as 
well as the port #.  If I just go through my normal server, 
I leave it blank.  Either way, HTTrack will not work with 
my reinstalled XP OS, despite my having uninstalled and 
reinstalled HTTrack several times.
