Full Tilt Poker Freeroll

I just wanted to register for the 250 U.S. freeroll but when I click on "register here button" that brings me to a page that says fulltiltpoker.com: "You must be from the United States of America ", which I am. I checked my information and said even the United States. Any help here? Oh and PS I signed up for other freerolls $ 250 U.S. before. Thank you for any help you can give me

Your IP address must be within the United States. They will do a reverse lookup on your IP to confirm that you are connecting from USA. If you're not, you will not be allowed to play.

If you try to work around this by using a proxy server located in the U.S., you may be able to get away. If you abuse this tactic to enter the other country specific freerolls, you'll probably be blocked (unless of course you've already been blocked).
