Are you the owner of said group? Admins can't delete a group. If you are owner click on the "contact us" button at the bottom of your page and ask CafeMom to delete it.

If the group owner is unavailable, just send CM a contact us report and let them know how it stands with the group. If you would like to own it and try to get it going yourself, they can also turn it over to you. Either you need to contact them.
