Not translating

Hi,

We have purchased wpautotranslate pro and downloaded it. We tried to install it but we get an error of a missing file in class-wpautotranslate-admin.php

wp_enqueue_script( $this->plugin_name, plugin_dir_url( __FILE__ ) . ‘js/wpautotranslate-admin.js’, array( ‘jquery’ ), $this->version, false );

It isn’t admin/js/ folder. This folder is empty.
At this moment only the post is duplicated but nothing translates.

plugin version: 2.1.0
roots bedrock setup
multilangualpress 4.0

can you tell us what goes wrong?

Await your reply.
Best regards,
Joris
