Dude, next time got question go to this thread, don't make multiple threads, read Rules & Regulation here. Sorry I'm too noisy >.<.


Answer: U copy your CD-Key at your house, then go to COD4 Multiplayer, go Options, then go Multiplayer option, and got Enter Key Code, then enter exactly what your CD-Key at home written. Then go out then copy your profile at home to COD4 profile in Blitzone.

AND remember, when you're playing in Blitzone, make sure no one playing at your house's, or else it would be crash.
