Visual Studio 2010 modeling project error

Question

I have serious problem with my modeling project, created in Visual Studio 2010. Today I was renaming my project and solution name and path's. And now it throws me some kind of error, when I wish to open any diagram. And then i role everything back to the first settings, but still the same.

Error:

Cannot load

'C:\Users\Klemen\Trgovina\Knjiznica\UMLUseCaseDiagram1.

usecasediagram': You must open this UML diagram inside the Visual

Studio modeling project that was used to create it.

Does anyone know, how to make my project work again?

Thanks

Answer 1

Do you have any Add-On/Plugin ? I had a conflicting add-on and after removing it, it is working again.
