No I haven't, Please let us know what they say, it came back wrong code for me.

Here's the resolution to the 3/30 code problem as noted on their message board.

Hi there:

Just wanted to let you know that since we had trouble on March 30 with the instant win page, we are instead going to award the March 30 prizes to random winners we select from among those who enter any other day of the week (from Monday March 31 through Saturday April 3).

So, if you participate in the instant win on any of those days, you could win that day's instant win prize, plus you'll be entered into the drawings for the weekly grand prize AND for the March 30 prize.
