Python error

I am trying to run the Linux dashboard and when I type: sudo ./droboview on the command line I get the following error:

Traceback (most recent call last):
File “/usr/sbin/drobom”, line 451, in
tb = DroboGUI(d)
File “/usr/lib/pymodules/python2.6/DroboGUI.py”, line 777, in init
File “/usr/lib/pymodules/python2.6/DroboGUI.py”, line 657, in __initOptionsTab
self.Options.DDRCheckBox.setChecked( self.options[‘DualDiskRedundancy’] )
TypeError: ‘NoneType’ object is unsubscriptable

What package do I not have installed. I am running drobo-utils-
