Can't open a .dbproj file from VSTS DB Edition

The title says everything. I'm using Visual Studio Team System 2008 Database Edition and I just can't open any database project. I get the following error message:

'..' cannot be opened because its project type (.dbproj) is not supported by this version of the application. To open it, please use a version that 开发者_Python百科supports this type of project.

Does this ever happen to you?

Thank you

Just found the answer to my problem here. It worked fine, after executing the following command:

devenv /resetskippkgs

May be it'll help someone one day :)
