When I set my hacked client to proxy server and click play, I connect to a realm but I get this error message in K Relay:

[Plugin Error] An exception was thrown
within a ServerPacket callback
at ReconnectHandler.getClient
Here's the exception report:
System.*********enceException: Object reference not set to an instance of an object.
at K_Relay.Util.ReconnectHandler.getClient(Client client)
at K_Relay.Util.ReconnectHandler.OnReconnect(Client client, Packet packet)
at Lib_K_Relay.Proxy.FireServerPacket(Client client, Packet packet)
[Client Handler] Client disconnected. (Time: 0)

How can I fix this so that K Relay works? Any help is much appreciated
