Leopard - unable to view network in preference

Just installed leopoard and encountered the blue screen of death but that has been fixed.

However I have gone to the wifi icon and it says 'Airport: Not configured' and when I go to 'Open Network Preferences' the Prefs appear but do not respond. I have manually opened system prefs and can access all prefs apart from 'Network' which the title changes to 'Loading Network...' and does not respond.

I have tried to connect to ethernet but it does not allow me to access the Internet (to prefore a software update). Anyone have this problem or a solution.

Many Thanks

 

This is not a 'bump', I am just worried that no-one else has had this problem
