ODS addon installation

Hi,
i’ve installed ODS engineering in blender 2.68 and the file is showing up in the addons section but when i try to check the box i have this error:
Traceback (most recent call last):
File"/home/lucio/Programmi/Blender/blender-2.68a-linux-glic211-x86_64/2.68/scripts/modules/addon_utils.py",line294, in enable
mod=import(module_name)
File “/home/lucio/.config/blender/2.68/scripts/addons/ODS_Studio.py”,line61,in<module>
from ODS import register, unregister
ImportError: No module named ‘ODS’

what i have to do??

The installation instructions mention using this addon with blender 2.63a. Have you tried using that blender version ?
