Hi,
I've migrated Source Safe solution over to TFS. However, whenever I try and add a file to any of the projects, I get an error saying:

"The item {projectpath}.csproj.vspscc could not be found in your workspace, or you do no have permission to access it"

If I remove all the SourceSafe files from the solution then click on the above error they all reappear?

I can update files fine but not add. I also exclused any SourceSafe files when I added the solution to TFS.

Any ideas on how to solve this?
Thanks
