displaying wrong

Uploaded a new version of my site, but some pages are displaying incorrectly.

If you go here

http://www.bloomsburycleaning.co.uk/index.htm

then click about us in the top right, you can see the nav bar has disappeared and the 'about us' link has turned into the 'events' button. I can't figure out why this is? The site has been uploaded for a few days now.

No problems here -- every page loads fine as well as the About Us page.
Probably your browser cache is serving old images -- hit F5 a few times or empty your cache before re visiting.
