You have to change the following line in Version.php (94 - 101):
public function getECBlocksForLevel($ecLevel) { return $this->ecBlocks[$ecLevel->getOrdinal()]; }

to:

public function getECBlocksForLevel($ecLevel) { if(is_array($this->ecBlocks)){ return $this->ecBlocks[$ecLevel->getOrdinal()]; }else{ return $this->ecBlocks; } }
