Do you have the hook "tpl_cc_usersettings" in your cc_usersettings.tpl template file? (you most probably have)
Did you enable "Allow users to choose to stop receiving group emails" in the module settings?
I think that are the two requirements for having the control center option show up. The option is added to the mail settings section of the control center.
