I pre-ordered at the start of April and was given these 2 keys. One for the pre-order stuff and one for the expansion. I registered both then, in April at the same time.
I tried to log into the game today and it said I wasn't registered. I tried both of those keys and neither worked.
If there is a 3rd key then I was never given it.
That key for the expansion pack was successfully entered and seemed to properly be accepted but now no longer does.
Still no customer support via email.
