My friend just bought himself a copy of Diablo 2 and the expansion and he is fully update and open battle.net keeps on telling him that his cd-key is invalid. please can you tell me why this might be happening and this is definitely a genuine copy of the game.

Unfortunately I can't help you with this, I can just inform you that many people have had problems with installing the new patch, including me. Reinstall everything - that's the only advice I can give

It could be that he possibly got a returned copy of Diablo 2, I know there's many a bastard out there that buys a game and then returns it to simply get at the CD key.

That or it's somehow one of the many banned CD keys Blizzard lopped down.

unforortunatly people use programs that randomly generate cd key for diablo like the diablo store so this cause the people to suffer cause the bought that random cd key

Blizzard has a special replacement key policy where if you send the originaly CD case with the CD key sticker attached they'll replace the key with a new one.
