Spry menu error in EI Disappearing List Background Bug

Question

I wanted to be able to update the menu once so I made the menu as a library item. At first the menu kept dissapearing in EI, somehow I fixed it so it actually does show up properly now but Dreamweaver is still showing the error " Disappearing List Background Bug in EI" all in the opening of the  <ul> . And now I have also noticed that there is an issue with the first menu, when rolling over the "company tab" it drops down the sub-menu and let you click on "about" it goes to the page but from there when you roll over the menu's they dont change color and they dont show the sub-menu. This work fine if I go to any other menu on that bar exept for the first one. I dont know what to do, and apreciate any help!

The reason the menu does not work in the about page is because there is no link to SpryMenuBar.js on the page.
The following shows the first few lines of your document for index.html
