im having problems with mine also, called clemson ticket sales, they resent the email and i still have not received anything, getting nervous since tomorrow is last day they can correct this, i called my email server and they said its the way they are sending the email, its bouncing around all over the place and not allowing my server to receive it.
I only received fanfest tickets also. not happy ticket office waited so long to get these out. Surely had to have allotment done before game. will call ticket office tomorrow...hopefully they can get this right!
