evernote PHP SDK not working for free account - php

Question

I have integrated the PHP SDK from Github: https://github.com/evernote/evernote-cloud-sdk-php
I have managed to connect a Premium account using Developer Token. It works a treat.
However, when I try to access more accounts, I get an error. Here is my code
<pre>
require_once '../libs/evernote/src/autoload.php';

$gMysql = new MySQL_Class(array("host"=>"localhost","user"=>"horscote","password"=>"feO#6i77","dbname"=>"horscote"));
$gMysql->connect();
$siren = $_POST['id'];
//if logged user - saved as viewed
$sqlViewed = 'SELECT evernoteSync FROM company WHERE SIREN='.$siren;
$isSync = $gMysql->queryValue($sqlViewed);
$gMysql->close();
if($isSync==1)
{
$gMysql->connect();
//get all admin evernotes
$evernotes = $gMysql->queryList('SELECT * FROM evernote_users e inner join users u on u.id=e.userid WHERE evernote=1 ORDER BY e.ID');

Any idea if all the accounts need to be premium? The premium account works but the others don't.
