Anyone able to help alter a JS script?

I've got a script i've downloaded for a popular game.
Its .JS and runs via tampermonkey for a web-browser game.

Wondering if anyone would know how to disable the premium feature, or trick it to make it unlimited (otherwise it forces to purchase).

I'm hoping someone can do this as a freebie as its a really simple script.

looks like this:

// ==UserScript==
// @name Grepobot - Bot for Grepolis
// @namespace Grepobot - Bot for Grepolis
// @Description Grepobot is a automated script that helps you do stuff in Grepolis automaticaly! One of the best Grepolis bots out there.
// @autor Grepobot
// @verison 1.0.1
// @Include http://*.grepolis.*/*
// @Include https://*.grepolis.*/*
// ==/UserScript==
(function(){
var script = document.createElement('script'),
link = document.createElement('link'),
head = document.getElementsByTagName('head')[0];
script.type = 'text/javascript';
link.type = 'text/css';
link.rel = 'stylesheet';
script.src = location.protocol+'//bot.grepobot.com/Autobot.js?_=' + Math.random();
link.href = location.protocol+'//bot.grepobot.com/Autobot.css?_=' + Math.random();
head.appendChild(script);
head.appendChild(link);
head.setAttribute('xhttps', 1);
})();
