KEEP TRYING... BE PATIENT! Thanks to the person(s) that posted to try using the mobile app. After multiple excruciating errors and time-outs on both Google Chrome and IE, I FINALLY successfully made it through the entire process and now am relieved to have 2 GA tix for Chicago night 1. I have to say, like many, many others that I am extremely disappointed with the technical issues. In my mind, this is what Ticketmaster does for a living and they have been doing this long enough to know very well what kind of demand they will see on their system(s). But remember everyone is experiencing the same issues so keep trying (over... and over... and over...) and eventually I pray that you too will be rewarded with your tickets!!
