problem with django-videokit-0.0.4

I am trying to use django-videokit-0.0.4 to be able to save videos in my models I follow the steps that they give me in the documentation but in the end when I run the server I get this error:

 Unhandled exception in thread started by <function check_errors.        <locals>.wrapper at 0x04EFE8E8>

please thank any help or comment. The objective that I want is to be able to save files like videos in one of my models as it would be done using Images if they know otherwise to do so.
