"Add" option missing commands in MVC 2 RC project in Visual Studio 2010

Question

I am working on this project which was created using ASP.NET MVC 2 RC. The "Add" has disappeared when I right click on the files. My problem is similar to this:

http://stackoverflow.com/questions/2136074/vs-2010-beta-2-asp-net-mvc2-project-cannot-add-areas

but the WalkThrough answer didn't help. example: "Add" option is there for "Controllers" folders but "Add -> Controllers" is missing. There is no "Add" for individual files at all.

Note: I do not have any problems if I create new MVC 2 projects. So the problem is not with the VS installation.

Please help!! Thanks

*not the answer.
The only way which I thought would work was to create a new solution inside the old solution and copy/overwrite all the files from the old one to the new one. I got the Add options back but got 100+ referencing errors when I tried to build/run the project. So don't try this.
