Aside from the flash size mentioned earlier, the page looks fine.
Just use Filezilla to remove the site entirely from your host, re-export from Web Designer to a folder on your desktop (so it's easy to find) then upload the lot with FileZilla.
When done, review with your browser and if some graphics are out of place, refresh (shift+F5).
Also worth checking with another browser (I have all browser installed so I can check that my sites look fine well in them all)
