Hi, I can't get the CustomBrowse plugin from Erland to work..

1. I've unzipped the 2.0beta13 version to the plugin directory and restarted SC7. I'm using the standard skin.
2. When I go to server settings, Plugins, I can see the CustomBrowse plugin and it is checkmarked ok. When I click settings for it, I only get HTTP 404 error.

What could be my problem?
Thanks for any help!
