System Preferences -> Network Not Loading

Hi,

I've a OS X 10.6.2 for a week now, and my Network Preference Pane wouldn't load all of a sudden. The last time I changeed it was the other day where I removed some wireless networks.

When I load the network pref pane, it just says "Loading Network..."

I created another user to check if it's just my user account, but it has the same problem too. So I would think it's a system-wide setting that went wrong.

My console log has the following whenever I try to open the pref pane:
11/24/09 11:05:52 AM System Preferences[1586] * Assertion failure in -[NSMenuItem initWithTitle:action:keyEquivalent:], /SourceCache/AppKit/AppKit-1038.25/Menus.subproj/NSMenuItem.m:270
11/24/09 11:05:52 AM System Preferences[1586] Invalid parameter not satisfying: aString != nil

Must be a setting in the plist, I just don't know which one, and how do I get that plist back without a time machine backup.

Please help, I've been all around the web and the discussions and can't find a solution to this one.

Thanks.
