question about cd keys / game versions

[fightclublegend]

Last night my friend decided to quit Diablo and he said I could have his cd keys to mule with. So today I used a cd key changer program but now I'm getting the error "The CD-key used to install this product was intended for a different product." So I'm wondering is the battlechest version of the game somehow different from the separately packaged classic and expansion versions? Or does anyone know why i'm getting this error?

Might want to check that your friend sent you the right key for diablo ... lol
