Serial key already used?!

[FLIPDUDE]

I signed up to the open Beta, using the serial posted on trackmania's facebook wall... but when I try to create a maniaplanet account it says the key is already used!

I try to log in using beta2 and the password given on the site, but then it says incorrect password! What am I missing here?

The serial posted on Trackmania's facebook's wall was for the fastest.
It means that someone was faster than you to enter the key into the game.

Wait the next key on facebook's wall and be the fastest to enter it into your game

Do you have another key to give away tonight or not? I have been trying to buy this game for the last week but the website payment is broken.

No i have no key, wait that the payement is fixed, or wait a key on the Trackmania's wall
