Just following in case anyone else bumps into this problem. Various suggestions on the web pointed to a fix by running...
devenv /installvstemplates (from the VS 2010 command window)

This did not fix the problem for me.

Uninstalling VS2010 and reinstalling, then also reinstalling MM.NET 4.0 solved the problem.

>I have been using MM.Net 4.0 in 64 bit Windows 7 for some time now. All the sudden the MM.Net project wizards are gone from the interface. When I click NEW | PROJECT and select MM.NET... I only have one entry and that is for 'Entity Framework Business Object Library' for c#. I used to have entries for Business Object Projects, WPF Projects, Windows Forms projects, etc. Now they're all gone.
>I still have the 'MM Business Layer Generator' under the TOOLS menu. And when I open my WPF project I still see MM.NET WPF controls in the toolbox. It seems like it's all there and working normal except the the new project wizards are gone.

>I have uninstalled and resinstalled MM.NET 4.0 multiple times. Both with reboots and no reboots... and no change. MM.NET Project Wizards don't appear. I have also reset the environment a couple times to test that. Still no results.

>Not sure what to try next. What could be going on? Any ideas how I can get my MM.NET Project Wizards back?
