Its a pirate CD or someone stole your key number.
But you can always make a server for other people to join, without telling you that the CD key is invalid. fabri405 - 10 years ago
Somebody else has used your cd key, so you either gave it out to someone or used a pirated cd key of the net. Flaming_Bubble - 10 years ago
