"You (the manager) need to login at least once every 3 weeks (so 21 days) in order to keep your team active. if you fail to do that, then your team will be closed down and converted back to bot team. Once this is done, there is no way to reopen the same team at any time in the future."


Try contacting the admins (click home, then bottom of column on the left hand side it says Contact Us) and they might be able to give you an extention if you let them know.
