Hi, I'm trying to work through the example of block development (http://www.concrete5.org/documentation/how-tos/developers/understanding-and-building-blocks-in-concrete5/) and I'm getting an error when I try and load the basic_test block. I've copied it into the blocks folder, when I go to Dashboard/Block types I get

Fatal error: require_once(): Failed opening required 'C:\xampp\htdocs\FFP\concrete/blocks/basic_test/controller.php'

I've done the JSON.php copy, that doesn't fix it. I'm running on a fresh install of 5.6.0.2.
