The document was originally created on a Windows Vista machine, the editing was done on a Windows 2007 machine, and I have tried to trouble shoot on my own computer, which runs Windows 2010 64, with Office 2010. When I try to open the document by double clicking it, the Word Logo appears, saying "opening in protected view", but then nothing more happens. Word never opens completely. Word has not frozen, because clicking "cancel" closes it down. If I open Word first, and open the document from "file - open" the same thing happens - "opening in protected view" and then nothing.
I assumed that the document had been corrupted somehow, but the really wierd thing is that Outlook 2010 is able to preview the entire file, and I am able to open it without any difficulty in Open Office 3. The the whole document is there, without any corruption. If I then save the file within Open Office as a .doc file, and a new name, Word is still unable to open the resulting file.
Can anyone help me work out what on earth is going on?
