1) Always post the ACTUAL command line used (or log file line two) so we know
what the site is, what ALL your settings are, etc.
2) Always post the URLs you're not getting and from what URL.
3) Always post anything USEFUL from the log file.
4) If you want everything use the near flag (get non-html files related) not
filters.

The default is to spider the site and get all files. +*.pdf changes nothing.
If you can open the directory in the browser, then so can HTT. Give the
directory url to HTt.
Otherwise, HTT can only get links by spidering the html. There is no magic
here.
