[restore registry keys removed]

I tried your link to Office diagnostics.  Everything worked until Setup diagnostics.  It just kept cancelling the Setup diagnostics.  When I am in Word and click on Mailings, then either labels or envelopes, I get this error message: "there is a problem with the label information.  You may correct this by repairing Office or by reinstalling label information".  When I researched, it says to run regidit.  I am too scared.  Any ideas how I can fix?  I have a small craft business and use labels and envelopes in Word daily.  Thanks.

I did a registry cleanup and files were deleted.  Did not do a backup.  Now my Office 2007 Word is not working properly.  And the Ccleaner was the only thing that could have affected it.  How can I restore the files or keys deleted or fixed?
