Which version of PHP library did you use?

I am testing with PHP SDK v3.11.0
https://github.com/braintree/braintree_php

There is a autoload php function. Error code:
Class 'Braintree_Configuration' not found in /var/www/html/application/libraries/Braintree_lib.php

When I use SDK v.2.40.0
Its work, but I sometime display error("Can't read raw data") and stop my php.
