Om någon råkar ut för "Du har redan löst in koden" så är lösningen här:
Ok guys,
I got the code already redeemed error. Signed up after WWDC. etc etc
I finally am downloading Yosemite. How?
Easy.
Scroll down to the end of the page. Click Leave Program. Leave.
Go to the beta program page. Click sign up. Enter your ID again.
It will give you a new code. Copy and paste it manually into the AppStore.
It will accept and start downloading.
Oh, also, it will give you the "We'll be back page" again and again. Just hit reload when that happens.
Apple. It Just Works.
