Sounds like the real estate site upgraded their shockwave/flash/something
version. Just go to macromedia.com and download new versions of
shockwave/flash. I'd suggest going back to the real estate site and checking
out what program they are using to create that stuff (as you probably don't
need to download both). It should say "to view this site, you'll need
_______," and it might be a link. Click on the link if there is one.
