Both glad and sad that others had problems as well with the pre-sale, codes and such.
After trying for about twenty minutes on 3 different devices and being told my code was invalid. Only to finally get Ticketmaster to accept it and get kicked out when I selected the seats I wanted to purchase.
Then a few more valid attempts to get the code accepted again, I received a notice saying the system won't let me select seats. At this point that fine I just want a seat. After a few "try again" messages it kicked me out again and now won't accept my code.
It's 1.5 hours into the pre-sale so I'm figuring it is a lost cause.
