then click the link i posted in the last post.
i have just registered an account, i have clicked the button apply for beta key, this is the page i get after logging into http://ghostrecononline.uk.ubi.com/
I always see a big yellow box to the right that says Redeem Beta Key, if you dont, click the link Here it SHOULD take you to the page where you can enter your key, if it doesnt, open a support ticket with ubisoft.
