python error with driver

Support Animation and Rigging

Hallo.

Im totally new to rigging and am following a rigging tut. Ive got a ball added some constraints and am now adding a driver to counter rotation. But im getting a error message for python. I have windows 7 and just downloaded python for windows but my driver is still not behaving as i wanted. Or instructed in the Humane rigging tutorial. I want to be able to rotate the Main empty ( so the square one) while the ball and second empty stay still. Ive added my blend file so u can see the python error in the left window. Does anyone have suggestions so i can continue with changing op systems?

hi.

Python is bundled with blender, you shouldnt have to download it separately.
The example file you posted works for me.
You may need to load the file as trusted, or enable Auto Run Python Scripts in user preferences.
See here for more info: Drivers - Troubleshooting
