This morning I created a new spread sheet, saved it and went about my business. about 20 minutes later I changed the name of the document through windows explorer (right click, rename).
Now, ALL 2007 file versions on this computer show up corrupted. All past saved documents and newly saved documents.
All compatibility mode items still open and save. It's just all 2007 versions fail. What has happened to my program? Do I need to reinstall?
Also, there are other workstations in this office that will open all these files in their current form. Not sure what is happening here.
