This is the same problem I am having.
i own 1.0 and just bought the digital pre order for the early access only lol and never got a early access code sent :(
anyone have any idea when i will receive a email with the code :)
I purchased two digital downloads for my wife and I from Amazon. I tried entering both of them in on the 20th, but right after entering the code I got an error. I later realized no one could enter their codes so I figured I'd try again on the 21st.
It worked on the 21st, I was able to enter my early access code which took me to a second code (completely different from the early access code). I entered that in and it asked me to verify the pre-order bonus to which I submitted.
When I tried to input the second early access code (for my wife on her account) it said the code was already in use. When I went to check out my profile page, it says I now have two games. One says it was registered on the 20th, yet no one could even register then, and I didn't get that second code on the 20th, just an error message.
Note: The codes I recieved from Amazon were not the same.
