How do I update Realm Relay

I setup Realm Relay but it gives me the "Waiting for HELLO from client..." thing and in another forum someone told me that I needed to update Realm Relay but all I can find in this section is scripts. Googling also did not prove to be useful Can anyone link me to something that might help me get Realm Relay working? I have looked on the forums and no one seems to give a straight answer on how to do this. If someone would walk me through it once I am willing to make a tutorial or write a script to automate this process.

I also need help with this so if anyone can help me and everyone else that would be great!
