Print Center not working!

Every time I start up print center on any user (even admin) other than root, it gives me an error saying:
"Print Center must run with administrator privileges."
Then in smaller font it sais:
"The print center software is not configured correctly. Please check and, if necessary, reinstall your system software."
I can open it under root, but when I go to add printer, it crashes!
I think this might be becuse I was messin around with the file privalages. Does any one know how to fix this?
