Upgrade code already used

I bought myself a copy of Factorio but when I got the upgrade code I got a message saying that the code was already used.

I bought the game but didn't get any activation code.

That's an answer to a completely different question, though. Yofaceismyface said that he already got his activation code, but it is not working.

Sending an email to support@factorio.com still appears to be a good idea, though.
