Visual Studio 2010 throws error when creating a Resource File

This is very strange...I get an error when trying to create a resource file in Visual Studio 2010...I have absolutely no idea how to fix this...tried googling it and came up with nothing.

I tried two different ways...right click on the Class Library Project, click the Resources tab on the left, then click Add default Resource file. A popup comes up with the following:

"Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))

So I tried creating a resource folder and adding a new resource item to that folder...same error.

Has anyone seen this error before or have an idea of where to start to try and fix this issue?

Thanks

I have seen this before (getting it right now). I get the same error when trying to view class diagrams. In both cases, I only see the problem when I run as administrator. I'm seeing many other similar issues (error loading project properties) running as administrator that other people in my team aren't (even when viewing the same stuff) so I figure it must be something to do with my install.

Update: reinstall worked a charm and I no longer get this error.
