Crystal mountain music festival?

At the area 406 music festival in Kalispell MT, I was handed an invitation for Crystal mountain music festival (near Darby, MT) with a link to purchase a ticket. However, they require a name and email address of a person who invited you to buy a ticket, so even though I was invited, I don't have the info I need to buy a ticket. Anyone else going who would be willing to help me out?
