I saw a first come first serve betakey for Elderscrolls which was posted 2 seconds ago (when i clicked on it). Applied the code and started filling in all the account mumbo-jumbo. At the end of the account creation the company asks you for your zip code ( I had already selected my country as United Kingdom where zipcodes are known as Postcodes). So I fill in the information about 10 times over and over again, and I kept being prompted with an Error saying that my zip code is invalid. so I had to ramble through Google to find a random American zip code; and by the time all that had been done the key had already been used by someone else. GG ME.

Tl;dr: gamesas Has no clue that People from the United Kingdom use Post codes and not zip codes, and I got Screwed for it. FIX IT PLEASE, so it doesn't happen to anyone else.

They're not sending invites to people from Europe yet, it's only the US for now. You didn't get screwed, it's how it works and it wasn't even your beta key in the first place. In any case, if you had received the email, you'd know this is not the place to discuss problems with registering for the beta - they have their own forum.
