So here's what happened. I purchased the HW US standard online and got emailed my registration key. My account is not steam. It isnt early access. It's just a regular US PC HW key. I log into the mog and click Enter expansion code and every time I do it says invalid. I tried entering it in early access and even item redeem just incase and it all says invalid. It is the registration code sent to me in the email. I quadruple checked it and tried it like 50 times over the next 2 hours and it still doesn't work. Does anybody else know what's going on?
