Visual Source Save and Visual Studio 2010 overwriting files

Visual Source Save and Visual Studio 2010 overwriting files

Visual Source safe and visual studio are somehow overwriting my files.
When I save files and close visual studio then open it back up my changes
are erased. I have already made sure that "Get everything when opening a
solution or project" is unchecked.
Any solutions on how to stop visual studio and VSS from overwriting files
