As we posted last night (and updated throughout the morning,) Lincoln Center started selling tickets for JK Rowling’s Live Chat 12 hours early. Today the venue has commented on the situation by saying:

Due to technical difficulties on the ticketing website, tickets for the J. K. Rowling event on 10/16/12 were made available prematurely at 10 pm on September 9th. Tickets then went on sale at the previously announced time of 10 am on September 10th. Jazz at Lincoln Center is in the process of investigating how this occurred and what arrangements may be made to honor each ticket purchased, and will provide an update as quickly as possible. Neither JK Rowling nor Little Brown and Company are responsible for this situation. Jazz at Lincoln Center apologizes for any inconvenience.

Hypable reports that, through calling the venue directly, “some representatives said that the tickets would be honored, while others were unsure and a few said that the Sunday night purchases were invalid.”  They also report that some seats may have been double-booked.  We will update again as soon as more information is available!
