How to change clientversion?

[tejdi]

I changed in modules\client_entergame\server to:

Module
name: addon_server
description: Single server and protocol
author: Fabricio Damazio

autoload: true
autoload-priority: 1000

dependencies:
-client_entergame

@onLoad: |
EnterGame.setUniqueServer("xxxxxxx[myip, hidden]", 7171, 1031)

but client always when i try to login says:
Unable to load dat file, please place a valid dat in '/things/1010/Tibia'
When i have got things/1031, and i want 10.31 client what is wrong?

Are you using the latest OTClient? I was able to use 10.31 in the latest one.
