I followed all the instructions to get my in-game bonuses, to a T. Got the 20 digit registration code. Went to mogstation. My account. Pre-Order Bonus Code (Early Access). Got to the bottom of the page. Entered in the code in the 5 segmented boxes. Invalid. Entered again. Invalid. Copied and pasted. Invalid.

I'm getting a bit frustrated, as no article online has any information but to do what I've already done. Can anyone help me?
