I have had lots of problems trying to play Halo online. When loading the level I want to go to (I have tried loads) I get the message: "Invalid cd-key" (some levels do work).
My version of halo is a copied version and I have got the original cd key. Online multiplayer did work until I tried to play my friend (who has the same CD-I copied it off him).
Is there a patch to fix this? Or how else can I fix this?
well gamespy realized theres two of the same cd keys runnign at the same time so what it did is it blocked one ip adress using the cd key and let the other one go, my sugestion is go get a new cd or go buy the game
