KRelay New Buffer Size Too Large

[makurell]

Trying to run KRelay from here https://www.mpgh.net/forum/showthread.php?t=1371239
I connected to the proxy server and I keep getting exceptions like this

[K Relay]        Initialization complete.
[Listener]       Starting local listener...
[Listener]       Local listener started.
[Listener]       Client received.
[Error]          An exception was thrown
within RemoteRead (isClient = True) 
at PacketBuffer.Resize

New buffer size is too large
[Error]          An exception was thrown
within ClientDisconnected 
at <>c.<Attach>b__1_0

Object reference not set to an instance of an object.
[Client]         Disconnected.
[Listener]       Client received.
[Error]          An exception was thrown

I updated the XMLs with the included updater, etc.
How do I fix this?
