Fatal Erro Q&A Plugin in Xampp emulator

I'm running Wordpress on Xampp , but I can not activate the Q & A plugin . When trying to activate the system displays the message:
Fatal Erro!

Fatal error: 'break' not in the 'loop' or 'switch' context in C:\xampp\htdocs\wp-content\plugins\qa\core\admin.php on line 438

I tried activation without any other plugin without success !

What I do?
