why does it always say keycode in udse?

why does it always say keycode in use?

i used some regedit from warez-bb and a keygen...

A keygen? lol, so you dont know much im guessing. If you got a key from a keygen, it means that some one else would have used it when they download the keygen. You wont be able to play on mnay servers, only cracked ones.

i sell yoo real cod4 key for $5

*edit*
