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 ted@tnellen.com with comments etc.

Finally
PLEASE BE SURE TO INCLUDE URL OF PROBLEM PAGE.

Cheers :)
