Sorry :(First, put the failed URL into the Way Back Machine to find the original file: http://archive.org/web/web.php
This is the first thing I would do.
Secondly, try playing with the .html and .htm of the file. Many times this is the problem, I have discovered.
I am more interested in linking to new URL location of the file than in replacing the file with a new file, as the intent of the original file link fits with the page as it was originally created.
Please contct the owner, Ted at firstname.lastname@example.org with comments etc.
