In the drop down menu under Config when i click on the motor tuning option nothing opens up.  Every other item on that menu will open except for motor tuning.  Re-install maybe?? please help!

Is the driver installed?
Try deleting the plugins from the plugins folder, assuming you dont use any. If you do then rename it to something like OldPlugins and make a new folder called plugins. Try putting the plugins back one by one if it does solve the problem.
