Please help me. I have a server on bluefang for me and my brother to play on and it has war of the walkers on it version v19.8.2.5b and our mod launcher has v19.8.2.5c I don't know if this is what is doing it but we can not team up. When i click on the player tab to join up with him nothing happens and when logging into the server I get an error message xui failed initializin window group players and object reference not set to an instance of an object. My spelling might be a little off :P. Can anyone please help me. I have tested out logging on to othere servers running the same mod and version and they same thing happens.
