Demoth - it sounds like you missed the free world transfer service that was offered earlier this summer, is that it? They split up the servers that existed at the end of 1.0 into NA and JP, so every 1.0 character could be transferred to the Legacy server of your choice at that time (either because you were now on a server in the wrong region, or because you just wanted to).

Depending on how long it was since you played/checked the game, you may have missed both the server mergers (for example, Besaid + Figaro --> Balmung) as well as the announcement about the free world transfer service. Whatever happened, I'm sorry you're stuck! On the bright side, at least they have better server stability?
