I attempted to purchase my tickets today at 12:00, using my presale code.
I made it to the end of the checkout and then there was an error when I tried to submit payment (I tried changing credit cards, address info) etc as I was trying to get my tickets in the 15 minute window.

Then it timed out giving me the same error: There was an error please contact support. And now when I tried to login in to the website again, I get "invalid presale code".

I'm super pissed off. And don't know what to do.
