after installing compiz I lost my unity feature and application launcher in my administrative login How can I restore it

[Mic Morris]

restating my problem. I installed and launched compiz. While attempting to engage some of the features my unity utility and application launcher disappeared in my administrative log account. I am also unable to log off or long on to another user account from this account. I can log into another user when on log on but if I log into my administrative account I am hung up and have to turn off the computer to exit.

Can you tell me how to restore the default unity in my account?
