I originally purchased the game on PS3 but regretted that decision, so I decided to get the windows copy when it became available on Amazon. Purchased it, downloaded and installed it just fine. However, when I go to the Mog Station, it says that the code that Amazon gave me is invalid.
Sent in a ticket and I am waiting for response, just wanted to bring it to the attention of others to see if more people are experiencing this issue, or just me.
