It sounds like you may have modified something (or your scripts did) that may have caused your lists not to work...
What kind of error message are you receiving from the list when you attempt to send do it, if any? From what address are you sending to the list? If it is an announcement type list, are you sure you have your email program's "From:" address set the same as the "owner" property of the list? Have you made any manual modifications to the list or any of it's files, or have you changed any of it's properties in the CNC?
This might be better as an email to
Support@FutureQuest.net rather than on the forums...
