I bought mine straight from SE Europe. I have the receipt email and the confirmation and content emails, both of the latter stating the early access code. It's always coming back invalid. I've submitted multiple enquiries, but of course, customer support replies appear to only exist Mon-Fri... I'm a bit disgusted that there's no customer support upon release of a purchased major update. It feels like SE have left me out to dry this weekend; while all my friends enjoy the new content, I can't even bring myself to log on and face the LS feeds of stuff I can't access.

So much for Early Access...
