[python-win32] Help with: pywintypes.com_error: (-2147418113, 'Catastrophic failure', None, None)?

>>> from win32com.client import *

    return self._oleobj_.InvokeTypes(-552, LCID, 1, (24, 0), (),)
pywintypes.com_error: (-2147418113, 'Catastrophic failure', None, None)

So, the util class Dispatches, but _all_ calls (properties and functions) give 'Catastrophic failure'
Is this really some sort of types problem with this OCX?

Thanks for any and all help,
Ray
