Of course these always happen when there is a deadline of some sorts. Our Registration Page wasn't working right for the last couple of days.
It's fixed now so everything is working. If you still are having problems, click refresh a couple of times to clear your browser and you should be good. I've extended the $800 sign up for a couple of days to make up for the hassle and give you time to register without the stress.
Sorry for the hassle,
Ken
