Stuart,

>The class viewer would not work. I uninstalled ModelingPowerToys and the class viewer started to work. I uninstalled and reinstalled MM and everything was work again. I could always create standard project and MM web projects, but not MM business projects or MM windows projects, could it have been the ModelingPowerToys?

Yes, that may be the problem. Unfortunately, the Class Designer PowerToys don't work with Vista!

Best Regards,
