I'm attempting to mirror files from <http://www.readynas.com/download/GPL>

I'm using linux command line httrack to ignore files I don't need.  
Code: #httrack "www.readynas.com/download/GPL/" -O "./www.readynas.com" -R5
H0Ko0s0zZd "+*.readynas.com/*" -*.zip -*.bz2 -*.tar -*.gz -v

Files in the www.readynas.com/download/GPL dir download correctly. However,
files in subdirectories below this level seemed to be cloaked.  They can be
accessed by my browser, but not by HTTrack.

Here is one of the Debug Lines:
(wizard) shared foreign domain link: link
www.readynas.com/download/GPL/index.php?dir=kernel-build-tools-x86%2F2.6.37%2Fpatches
at
www.readynas.com/download/GPL/index.php?dir=kernel-build-tools-x86%2F2.6.37

HTTreck creates html files of the subdirectories, but does not download the
files.

If I download a files from one of the directories directly, the link is
reported as <http://www.readynas.com/download/GPL/kernel-build-tools-x86/>. 

I created a cookies.txt and disabled the robot.txt, but neither seem to help.

Any help/suggestions are greatly apprecated.
Thanks
