All my menu extras are gone except for a third party one (weatherpop). All of the ones i used are still located in the correct folder, however none work. How do I regain this functionality?

sure you didn't just turn them off?

You can turn them back on from their respective control panels/applications:

battery: energy saver
clock: date & time
monitors: monitors
sound: sound

chat: iChat
keychain: Keychain Access

I think you may have a problem with the SystemUIServer, located in:

'/System/Library/CoreServices/SystemUIServer.app'

Replace it with the original from the Mac OS X cd. You can easily extract it with Pacifist.

as Arena says ... its the SystemUIServer.app where the problem is...
