the only thing i can see when i log into my account is to enter a retail serial code to continue my sub.
i'm taking a look at that link just now though.
doesn't seem to have the direct update button anywhere it would seem, only
"Your World of Warcraft Trial ends in -1 day(s). If you wish to continue playing with this account after the trial period ends and to enjoy all features of World of Warcraft, such as reaching the highest character level, unlimited chat and mail access, and taking part in all the epic adventures the game has to offer, simply purchase a retail copy of World of Warcraft and enter the Authentication Key in the boxes below."
