Uh, you really should be talking more with your "computer guy."

Word 7 = Word 2007? The one with the Office "pizza button" instead of the File button?
What version of Word do I have? by Shauna Kelly

If so, under the Control Panel for Programs and Applications, find Word 2007 or Office 2007 and choose to modify or change (not uninstall). You should be given the option to repair. Choose that.

Keep in mind that Office 2007 is no longer under any kind of support from Microsoft.

See if your computer guy can get you all of the patches and updates that have been done in the past ten years+.
