I've  been using OS X Lion (clean installed) on my Macbook Air.

Today, I activated "Guest User" loging.

After I "deactivate" it, I no longer access "Users & Groups" on the System Preference.

I just get:


Preference Error.

Could not load Users & Groups preference pane.


Has anyone had the same experience?




MacBook Air, Mac OS X (10.7)
