I've received a code where do I go to redeem it?

You should have received an email with the link to download the game, Click on that link, then 'apply for beta', then sign in with your Uplay account and then the redeem code box shows up.

I'm from US and having problems redeeming the code

Please have a look at this post http://forums.ubi.com/showthread.php...=1#post8174481 if you are still having issues please contact Customer Support here http://ghostrecononline.uk.ubi.com/support

I have no access to the Private Beta forums

Typically you should keep all technical issue discussions in the private beta forums.
