WP-Autoresponder

Hey folks,
I've been using a plugin called WP-autoresponder and I really like it. I'd like to offer it to my members but for whatever reason the plugin doesn't work properly in the sub-blogs. It's visible in the plugins list and you can activate it but the tab that controls the plugin i.e. settings, list management etc. doesn't show up at all for the sub-blog admins only for super-admin.

If someone could help find a work around I would greatly appreciate it.
