Model Doesnt Load..!

[eluser]ashipj[/eluser]
I have code

Code:

$this->load->model('DTO/ResponseDTO');

in my controller and i have my ResponseDTO.php class in "model/DTO" directory.

But when i run the application. I get the error

Code:

Fatal error: Class 'Responsedto' not found in C:\Program Files\xampp\htdocs\php\libraries\Loader.php on line 184

Its just for this class. Other Model classes are loading fine. Is it anything with the name or something..?

Thanks for reading
