So I bought FFXI six years or so ago. At this time i had a bad computer so i got it for the ps2. I just started replaying under the false assumption that Square would not be jerks and actually provide an ultimate collection for PS2 but that privlidge was only for 360 and the computer

anyways my question is, i started an account on my ps2 if i bought the ultimate collection for the computer (i now have a better one) can I play my existing account on my computer instead of my PS2 from now on?
