Can't add data files when creating new Profile in Mail Control Panel

After installing Outlook 2003 Security Updates, XP Service Pack 3, PowerPoint 2003, and other updates, I could no longer start Outlook--received this error message:

"Unable to open your default e-mail folders. An unexpected error has occurred. MAPI was unable to load the information service mspst.dll. Be sure the service is correctly installed and configured."

Also, when attempting to enter a new profile on Control> Mail, my system would lockup.

Googling my problem, I ran across this forum and this thread.

After following your suggestion: "start > run > outlook.exe /cleanpst > ok button", I was able to start Outlook and, like magic, all my problems were solved. I did not even have to create a new profile.

Many thanks,
