Ok, i just found my missing presale code. If you have any of the emails from u2.com for presales for any of the shows all you need to do is scroll down and your access is at the end of the email, it looks like when they notify you by email for any presale shows it includes your access code automatically. So if you havent got any of the old emails for show presales, im fairly sure when you receive your presale notification email later for the Dublin /Belfast shows it will include your access code.
