Nrelay error, need help

I just installed the dev version of nrelay and it was able to update successfully and automatically downloaded GroundTypes.json, client.swf and Objects.json

However, when I run it I get these errors:

[20:45:51 | usw3bot] Received failure 0: "server.update_client"
[20:45:51 | usw3bot] Received failure 4: "X24.0.0"

Any help is appreciated!

This error occurs if the "buildVersion" value in your acc-config.json is not the current build version of the game.
To fix this, simply open your acc-config.json and edit your buildVersion to say
Any time the game updates, you should make sure you also update this value in your account config.
