No I did not test it... and it did not work for me either, to just disable
robots.txt rules. 

However, I succesfully mirrored the web page in question by telling HTTrack
to:

1: Ignore robots.txt rules 
2: Set the user agent to "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"

From the command line it is done with these parameters:

-s0 -F "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"
