I downloaded the game today and got my serial key for it. But everytime I try to register the game with that serial key it tells me that I can only have 1 account on my pc. So I tried to use the email and password that I set up in order to use the forums and it tells me "Invalid username or password. I even tried clicking forgot password and it told me that there isn't an account with that email. I added screenshots of the errors. Please help. Thanks.
