Render Bell Addon not working

Hey everyone

So I tried to install this script so I could go in other rooms and hear the beep when my render was done but I got this message->

Traceback (most recent call last):
File “C:\Program Files\Blender Foundation\Blender\2.68\scripts\modules\”, line 307, in enable
AttributeError: ‘module’ object has no attribute ‘register’

Any Ideas?
I have installed other addons before but this one does not seem to be working :frowning:

I downloaded it from these two

Hi Thebucklayminer,

This is my addon working on Blender 2.68a(in my “addons_extern” folder): Link
Run very well!
