Attendees may not have their e tickets for a number of reasons. Unfortunately due to the amount of e tickets issued we are unable to reissue you with your e-ticket once it has been sent.
E tickets are sent to the email address on the original order form. Unless we receive a bounce back we take this as the e ticket has been delivered.
However this does not mean you cannot attend all you need to do is bring proof of payment and ID to the missing e-ticket desk at the convention you are attending. It's very straight forward.
