Hi I´m novate in Jarvis sorry. I have the problem with the following error:

Fatal error: Class 'Jarvis\Template\Builder' not found in C:\wamp\www\thd_3_4_8\templates\ot_enterdesign\index.php on line 3

In the line 3:
<?php
use Jarvis\Template\Builder;
$builder = Builder::instance();

I have installed the package Jarvis_Joomla_Template_Framework_1.1.0r75
