Invalid Code?

[nasolox]

I bet you have Steam Verison of the game...check to see if you have Steam Wallet in Mog Station account. If so your code from amazon will not work. I had the same issue. Trying to get refund now from SE store since i had to go purchase another copy on Steam. ) Also it should be 20 digit code. The 18 Digit code should of sent you to a website...that takes it and gives you back a 20 digit code.

Neither I nor him have steam or the steam version of the game. I checked the product it sent to my email and it send me to the redeem your code website with that code. I plug the code in as it told me and get either "invalid code" or "code has already been used." I tripple checked everything before buying specificaly to avoid buying the wrong thing. It's definitly the right product its the website that has done something odd..
