Reign of the Undead - Revolution

2 is a friend of mine came up with an error that is not level 1 started, but much nagyobbról. Recently Matthew0220 go up to the server, (he is a new player, though 136). I searched and found the user with which he plays. (What I received, for some reason, he went up to the server) (https://modszombies.com/page-playerstats/?u=329) However, the names are not written anywhere.
This not only think they have occurred but for others as well.

has he ever played with those names?, he have a private cd-key? Or it is public?

You've never played either one of the players on a server. They went immediately and with other users (levels) started. I guess because the game is not original.
I suppose the same CD key is used for both players, so the server thinks you went up to the same person, just different names.

If the CD key is not original, I cant do anything

Hmm. Okay, thanks. Why was deleted my user?
I wrote, the two friends did not happen to me. I have the original game. (Steam version)
