keep getting the following error when adding a block. It is just a copy of the original html block. I can't remember for the life of me what I have missed lol

updated the html controller file with appropriate names.
And created/updated the concrete/core/controllers/blocks/html2.php

If any one can point out my stupidity that would be great thanks lol

oh and here is the error:

Fatal error: Class 'Concrete5_Controller_Block_Html2' not found in C:\wamp\www\website\c5\blocks\html2\controller.php on line 4
