CD Key - Help please

[metalfreak]

hello everyone .. I'm trying to play multiplayer and when i'm trying to join a server it comes up an error message all the time: "CD Key In Use. Try reconnecting later" . I try many different keys but the problem is still the same :dis: Can I do something to fix this problem with the key?
