Microsoft Word 2008 problem - not opening latest version of document

Hello,

I am running Microsoft Word 2008 on a MacBook Pro, OS 10.4.11.

I having been working on a new document in Microsoft Word, containing an Excel chart since 11:45am today and have been periodically saving the file all day. I have recently reopened this document and instead of the latest version, it is loading the original 11.45am one (I have looked at the timestamp of the document in the 'Finder') - making it appear that I have lost all my days hard work.

Have I really lost it all or is there some kind of versioning system that I have overlooked?

Any help would be greatly appreciated please.

Thank you

After the original save, are you saving your work as Save As or still just save?
