you
CAN NOT have two MoW multiplayer accounts with
one CD key.
contact GameSpy support to get your "correct" MoW account with "correct" password. i think when you send them your MoW CD key its possible to see what gamespy account is bounded with this MoW CD key.
ps. i dont know why so much people dont make
any notice about registration/e-mail/passwords...
after first reinstall from operating system or game they will get problems with registration + passwords.
