Hello, I was working with an Excel document from the SharePoint 2010 with my Windows 7 and office 2007 when there was a power outage.
Since this when I try to edit the Excel I get the warnning: "There is a newer versión in the server, Do you want to work with this?
If I rename this Excel and upload to SharePoint I get the same issue.
If I create a new Excel, upload and edit from SharePoint the same issue.
IF I try from another computer, Win8 with office 2013 it works fine.
If I try trom another computer Win7 with office 2007 it works fine.
