got 2 tickets but not really happy with the placement, i'll try again on friday!

Hi guys I'm so sad right now!!! Had to create a new account. Impossible to remember and password and my email address is no longer accessible because I've changed provider .... if anyone could help me out for the presale code. I just don't know what to do. If someone is not using it please think of me. The last song my mum listened is uprising. I desperately want to go to manchester. Otherwise can I contact an admin or support service? Thanks again.
