Could not communicate with Internet Security

I am using NIS 5.5, OS 10.8.4 and VMWare Fusion. I had to reinstall VMWare tools yesterday to solve a printing problem. Today I could not access Norton Internet Security. Coincidental??? I have reinstalled NIS 5.5 three times. I get the message "Could not communicate with internet Security. Background Application is not running."

 

Any suggestions?

Solved it myself. I forgot to do an uninstall before reinstalling.
