The reason is a .zip file redirecting to another page. As 
httrack downloads contents AFTER creating links, such case 
is not handled correctly.

ct=http%3A%2F%2Fwww%2Ecodeproject%2Ecom%2Fwtl%2FXPControl%
> 2Easp&mode=1

But the redirect page seems to ask for a login username? 
Maybe using a proper cookie or "capture url" would solve 
the problem?
