I say "possible" because I'm not sure it didn't work...
I use a small set of names/passes for many things(yes, yes, I know); my
station account and the former MXO included. My problem is I don't
exactly remember which password I used for the WBIE(?) account, though
I am sure they had the same name. And when I tried to convert the
account using the password which was the one I thought it would be, it
said my station account already has access to MXO-- My problem is that
I don't know if I'm being logged in to the game with my station account
or the old WBIE account, because their name/pass (may be) is the same.
My question, which would solve this riddle for me, is: Do the old
accounts still work-- Are you able to log in and play if you haven't
converted? The FAQ suggested not, but I didn't clearly read it that
way... So, anyone know for sure?
