Emergency: My flight can't leave the airport

[Alex Jurgensen]

Hi,
Listers,

I am tethered to my Airport via my Macbook running Airport Utility. I  
made changes to the configuration, and now I hit update and it has  
been stuck for hours on Validating Airport Configuration. What can I  
do? I need to take my Macbook with me tommorrow to school, and can't  
afford to have it still validating.

Thanks for listening,
Alex,
