I am on version 2009 sp4.0.  All of a sudden, solidworks will no longer save anything.  If I start a new part file and before creating anything, I first save the file.  It wont even do that much.  After clicking on the save button, it returns back into solidworks and no file was saved.  It also occurs on assembly models as well as existing models.  I have restarted my computer and did a repair of my solidworks installation without any progress.  Any help/suggestions would be appreciated.

Thank you
