I decided to buy a 2nd copy of FFXI through Steam in order to have 2 accounts, so I bought the Abyssea Collection. However when I attempt to register the code on my 2nd SE account it can't do it and mentions about having to use a code that begins with a U. This one doesn't, and what's more if I try and add it to my first account it wants to merge it with my existing FFXI account. Help!
