APPARENTLY MY WINDOWS VISTA WAS CORRUPTED AFTER I UNINSTALLED NIS 2009. THE NORMAL UNINSTALL DID NOT WORK. I WAS PROMPTED TO DOWNLOAD AN UNINSTALLER FROM COMCAST WEBSITE THROUGH A LINK PROVIDED FOR ME. I DID. SOON I COULD NOT OPEN MICROSOFT OFFICE 2007 COMPONENTS. THE MICROSOFT EXPLORER SHOWED ITSELF AS INSTALLING THE PROGRAM, THEN IT REPORTED NOT BEEN ABLE TO, DUE TO SOME FILES MISSING. ANY SUGGESTIONS, PLEASE?
