2 copies of bc2

[lanzarobbie]

Hi i installed bc2 from dvd, but when vietnam came out my friend gifted me bc2 on steam so i could buy vietnam on steam, ive still used the original account to play.

I want to give a copy to my brother, is this possible?

Thanks

But isnt that locked to my steam account?

tried that, it says its invalid?
unless the copy im using has switched over from dvd key to steam key?
