Urban Giraffe Support

After adding the redirection folder to my plugins directory and activating, I go to Manage\Redirection

If I click on any of the links, I get a 404 error that the resource was not found.

If I hover over a link, say Logs, here is the URL:
http://sitename/wp-admin/edit.php&sub=log
Notice there is not a ?page=redirection.php

If I type the following url in the browser, then the log page loads.
http://sitename/wp-admin/edit.php?page=redirection.php&sub=log

Any suggestions?
