Yeah, unless you try the game first, and then subscribe to it by a conventional credit card, it won't set a Parent Password. I believe you'll need to call Toontown (1-888-332-1626) or talk to them on
Live Chat. (Toontown Live Chat is available from 10:00 AM to 2:00 PM, and from 3:00 PM to 6:45 PM -- Pacific Time -- Monday through Friday.)
