Computer gurus, please help me troubleshoot a pc issue

[kemper mentor]

Every time I log on under my name,  a message from Microsoft Word 2002 pops up:
  "The feathure you are trying to use is on a CD-ROM or other removable disk that is not available.  Insert the 'Microsoft Word 2002' disck and click OK."
   
  If I click the cancel button, then:
  "Please wait while Windows configures Microsoft Word 2002."  
   
  It configures (I guess), allows me to use an effed up version of Word 2002.
   
  We bought the system with xp operating system, but I forget what Word version (I think it was Office xp.)  We bought it in January 2005.  And I think we had the newest version at the time.  (A dog made lame suggestions instead of a paperclip)
   
  When my wife logs on under her name it's similar, except when she goes to save a error message pops up (something about C++ and a library)  If you 'x' out or hit ok, it will terminate the word session.  When you try to open it again, what you've typed has been recovered but you can't open it without the same error message and close out occurring.   
   
  I tried going to Microsoft, but found that I was not able to articulate effectively my problem in 4 - 10 words.
   
  Thank you to all.
   
  Kemper, who feels like he's babbling
