Some time has passed since the time of the terrible sources of security, but I believe that this is what you need to do. In Visual Studio, go to File -> Source Safe -> Change Source Control (?). He will open a new window and list the projects under the current solution related to Source Safe. Select the project you want to delete, and click "Unlink" at the top. It will remove the original secure bindings from the project. If you need to bind again, just click "Bind" and select a location in the repository to bind.
