OK. I tried to reinstall KOrganizer. That didn't work. Then I checked my Calendar profiles in Kontact. I had one that wasn't configured, so I deleted it. Then I restarted KOrganizer. That did the trick. I guess Kontact was attempting to open the top Calendar profile which was not configured. Once I deleted that from the list, Kontact automatically selected the next on the list. It works perfectly now.
I think this can be listed as solved. It was an easy fix. It only took 5 minutes.
