When I log in I get the choice between Choosing Final Fantasy XIV 1 and 2.
It's all in Japanese though and I can't tell via the mog station what the difference is supposed to be.

Is there some way to verify that I didn't buy 2 accounts?

I was in the beta and used 1 activation code then I preordered and I kept getting a lot of other activation codes. now I see 2 accounts. 1 Account appears to have all the beta characters I made.

The second one does not.
