I am getting this error from my controller call to a viewmodel: "OutOfBoundsException [ Error ]: ViewModel "View_Abouttwp" could not be found." This is the line in my controller which is flagged in the flow:

ViewModel::forge('Abouttwp');

This is the viewmodel code in the file at app/classes/view/abouttwp.php

<?php

/**
 * The abouttwpm view model.
 *
 * @package  app
 * @extends  ViewModel
 */
class View_Abouttwpm extends ViewModel
{
 /**
  * Prepare the view data, keeping this in here helps clean up
  * the controller.
  *
  * @return void
  */
 public function view()
 {
  $messages = array('Aw, crap!', 'Bloody Hell!', 'Uh Oh!', 'Nope, not here.', 'Huh?');
  $this->title = $messages[array_rand($messages)];
 }
}

I've checked the spelling, capitalization and underscores and they seem to match the documentation.
The files actually exist in the correct (I think) directories and access rights are correct.
Can anyone suggest where the problem lies?
