During the last beta weekend event I received a beta key. I made an account and linked that account with that given beta key. After the event I went and pre-ordered the game (the authorized retailer said they were completely out of pre-purchases, so please do not confuse the two). With the pre-order I get an in-game item and one day of headstart access. However I am running into an issue when I try to add the key given on the Pre-order card. I have looked through all the account settings and options looking for a location to add the key to my existing account; the one I created for the beta weekend and linked to my Guild Wars 1 account (at least I believe so), I cannot kind such an option.
I tried making a new account with the key and after putting in my birthdate and display name I receive error 502 - Web server received an invalid response while acting as a gateway or proxy server. Is that because I am trying to make an account with the credentials that are already in use?
I am looking for a way to add my key to my account and make sure that my Guild Wars 1 account is linked to it. Is the way to link them clicking "yes" on the "Do you have a Guild Wars account?" on the first screen of registration?
Thank you for the assistance in advance!
