Yes. Apparently it's one of the new set that starts this Saturday. For some reason it was available to enter today...you just can't play it until Saturday.
Given that, you have two options:
1. Wait until Saturday and play it.
2. E-mail Customer Service and request a refund of your entry fees.
For the record, I went with option #2, and it was sorted within the hour. Two thumbs up on that one. :-)
