I had some issues with the Ticketmaster website yesterday as the page timed out on my card verification page, and had to go back and start all over again. I've had my confirmation email etc now, but I also had another email from Ticketmaster a couple of hours later saying that they'd had to release my tickets as I'd not completed my transaction. That must have been the first two I tried to get. So KEEP TRYING because you never know, you may just be lucky enough to get tickets just as they release them from someone else... I had the same thing happen trying to get Foo Fighters tickets before. Nearly two solid hours of trying to get tickets, to no avail, and then I randomly checked the site about five hours after the tickets went on sale and was lucky enough to get two! Good luck!
