Page missing footer when viewed from Windows

I made a site in Dreamweaver on a Mac. It looks fine from a Mac, but from either IE or FF in Windows, on the following page, the entire bottom section (footer, etc., under the contact form), does not show up:
http://davesguitarplanet.com/GMShtml/_contact/contact.php

It's supposed to look like all the other pages; for example:
http://davesguitarplanet.com/GMShtml/

Any idea what's going on?
Thx

They look the same to me with IE9, Firefox 10.09.1 and Seamonkey 2.8 (Mozilla).

What does Dave's Guitar Planet have to do with Global Menu Solutions?

Nothing. It's just where I uploaded it for testing.

Thanks for looking!

This is IE 10, running from Windows 8 consumer preview. The pages load promptly, graphics are brilliant, whole page if available including footer.
