Crysis MP is using Gamespy and if you already have a Gamespy account it remembers/adds the key (permanently I guess) to that account. I've had no problem installing and playing Crysis MP both on XP and Vista but in both cases I used the same account/pw/key.
That's the problem...I can not find my manual.
