This means that somebody has registered an account with your name. You will be able to tell who it is by going to mxslobby.com/YourUidHere (for example mxslobby.com/2445). If you are truly the owner of that UID please create a support ticket. We will ask you to verify your ownership of the UID by connecting to an MXSLobby server.
Why does it say my UID is taken when I try to create an account?
