Please becareful where you are going to input your codes, this happen to my account having 2x Final Fantasy XIV Service Account in one Account.

One being from Closed beta/Open Beta, another is the Retail version.

In my account there is two Final Fantasy XIV, Final Fantasy XIV 1 and Final Fantasy XIV 2, my Final Fantaxy XIV 1 is inactive because i go and input into a new Final Fantasy XIV service code.

This is where you should be very well aware, that when PS3 comes out.. .

I think it will goes this way, got to ur current Final Fantasy XIV Account Service that is active, and use the Option List instead of inputing a newer code.
