A thousand thanks for this post. I had the same problem and just spent an ungodly amount of time trying to troubleshoot a solution; even had to call in my tech-savvy youngster to assist, without success. I should have known I would find the answer here! You just made my day, thank you!I had the same problem. No confirmation letter and Ticketmaster had no record of my purchase. Bought my tickets through the FOFS presale and to access them you need to download the NHL app and then hit the Predators link. The tickets will pop up and you can use your Ticketmaster password to access them to download on your mobile device.
Found all of this out by emailing Bridgestone Arena box office and receiving a response from Logan VanSickle (Ivansickle@powersmgmt.com). He was patient and sent explicit instructions.
