I LOST MY CONCERT TICKET!!! Please help, concert is in 2 days!! :(?

I got tickets to go to see The Script at the Aviva stadium for Christmas. Concert is on the 3rd of July and I really have searched EVERYWHERE and can't find it. Ticketmaster say that since there is no seat number (it's a pitch ticket) that they can't do anything. They cost 45 euro and I'm really upset. Plus my 2 friends both have their tickets, is there ANYTHING I can do? Please help.
