Main Menu Display Incorrect- Hover Background Off

Made the site public. Sorry about that, mate.

Can be viewed below.

I have pasted my current navigation.cc below.
The error is still there... it's actually gotten a bit worse. Could the padding be throwing off the hovering elements?
Sorry that I can't be of more use :( I'm still figuring out how Drupal does theming.
