I can't Join "February 2010 Banded Threesomes I 0-1150"

I get this ad:

"Sorry, you are not eligible to enter this tournament. This tournament is restricted to people with a tournament entry rating between 0 and 1149. Please see your profile for details of your tournament entry rating."

I'm 1143 from yesterday afternoon.

I tried again few minutes ago and I entered the tournament... uh...

Please note that your tournament entry rating differs from your actual rating.

"Tournament Entry Rating is calculated by the formula (CurrentRating + HighestRating) / 2. The entry rating will never drop to more than 100 points below your Highest Rating."
