Here is the issue i'm running into.

I was playing fine up until last night, then i go to log in this morning, says i need to register my account and put in my 20 digit code for the game, so I went to my code i used to get into the game initially, and says the code has already been used... I did receive another code about a week and a half ago, and whenever i try to put it in, it says :

"The code's region is inapplicable.
You can only enter codes from the same region as your Square Enix account. "

Whet do i do? Do i have to buy the game again, do I wait, or should I try and call their support line (do they even have one)?
