[Zope] Locked out of acl_users

Not realizing what I was doing would be a _bad_ thing, I mistakenly changed the default manager account to a ownership account. All other users are ownership, not manager. Now, I cannot get into acl_user regardless of what user I try to log in as. I keep getting: Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not authorized to view this object. ~~~~~~~~~ Is there any way to get myself set back up as a manager? :-) thx, Kevin
