Unfortunately, the Blizzcon Sweepstakes are being hosted by another website, Frenzie, and I'm not sure where is best to report this error at this time. In the mean time, try to clear out your cookies and cache in your internet browser, or try a different browser, and see if that helps.
If I receive any more information on where to report these issues, I'll let you know immediately. >^.^<
