Cider type initializer error

On one of our machines we are getting an error with Cider, after we create a new project, and try to click over to design mode, the following error prevents the design canvas from displaying:

Error 1 The type initializer for 'AvalonAdapter' threw an exception. C:\Projects\cider2\cider2\Window1.xaml 1 1 cider2

We have gone as far as to completely uninstall Visual Studio, all of the WinFX components, run the uninstall script, the cleanup script, and then reinstall Visual Studio, then MSDN library, then the WinFX components, then the tools, and the same error appears.

Any ideas?
