It doesn't look like splits have been uploaded for that event yet. While it is possible to create a new event and enter them yourself, please don't do that. Wait until the weekend is over and see if someone with the data files uploads the entire event's worth of splits.
The first thing you should do is go to this event link:
http://www.attackpoint.org/eventdetail.jsp/event_7...
...and say, "Yes, I'm going" in the little pull down menu.
When the splits do get uploaded, you have to claim the splits. I think you need your SI number to do that (although there is an option for people who use rented chips). Hopefully that number is in your event packet or on the splits sheet you got when you downloaded.
