Error getting started with WPF RadGridView

[Kin]

I just installed Q3 RadControls for WPF demo with VS2008 Pro on Windows 7.  I am attempting to follow along with

http://tv.telerik.com/wpf/radgridview/getting-started-with-radgridview-for-wpf

and am hitting an error immediately.  When I drag the RadGradView from the Toolbox onto the Design window, I receive a lengthy error dialog:

'Telerik.Windows.Controls.GridView;;;Component\Themes\GenericOfficeBlack.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'.  '/Teleric.Windows.Controls.GridView;component/themes/office/black/GridViewToggleButton.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'.
Object reference not set to an instance of an object.  Error at object 'System.Windows.ResourceDictionary' in markup file 'Telerik.Windows.Controls.GridView;;;Component\Themes\GenericOfficeBlack.xaml'.  Error at object 'System.Windows.ResourceDictionary'.

(This is a fresh install of VS 2008 Pro ... I haven't tried anything else with this config, and no other Telerik demos are presently installed.)

Any ideas what might be causing this?  Did I miss an install step of some kind? 

Thanks!

As followup ... I did manage to work around this.

Most controls seem to work just fine.  If I drag in a RadTileView, then follow that with a RadGridView, and then delete the RadTileView ... it all seems to work.  Don't know what the matter is ... but at least I can get it to go.

Same here and I've been able to workaround the same way. I have another issue too. I can only use the RibbonControls on my Windows XP machine. I get an error when I try to add the Dlls on my Windows 7 computer.

Any ideas?
