Cant open system preference !

[xxRONNIExx]

Not sure what happened. Tried to open my "System Preference" this mourning and I can't. I get a box telling me "You cant open the application system preference because it may be damaged or incomplete"...
I have no idea why this happen. Whats the best way to fix this issue?
