Now that I log in it says that I need to install the expansion which I have been playing for almost a week now on the same system.

If you go to the mogstation and try pressing the "register code for expansion" button what you will see is that the spaces in the code are for 20 character to be input in 4 sets

However none of the 3 codes are in this format!!

I have BOUGHT the game I have PLAYED the game but now I'm completely cut off because I logged off in Ishgard. What am I supposed to do now?!
