You need to create a Steam account, then once you do that, you need to register your CD-key so that Steam will download Half-Life from the server and update it to the latest version.Gh0st said:GRrrRR man i hwe install it but still i cant log in the server ...
Invalid also happens when you use a key you got off the internet by a keygenerator ^^MC said:If the CD-key is invalid that doesn't mean it's in use, it usually means you typed it wrong or have the wrong CD-key.
Each of us have told you many times... The only legal way to get a new key is by buying a new copy of the game, not a used or borrowed one.Gh0st said:and if you find somwey to get a CD key tell me :] c'ya
