Underworld Central Park ticket problems

[monochrome]

So, I was just at ticketweb finally buying my ticket for the september show, and just as I was submitting my order I got an "error has occurred" message, and now the show doesn't even come up when I search. Any idea what's going on? I must go to this show. I've been waiting to see Underworld for
about nine years. Is there any other way to get tickets?

Let me know! I need some help.
