Can't use IWDBarChart UIElement

I am running NW2004S SP 09. I am using version 7.0.09 of the NWDS.

My problem is that if I include a BarChart component (IWDBarChart), I get the following exception raised:

Am I missing something or is there something in particular I have to do to utilize these analytic components?

Thanks in advance.
