.zip? There are no .zip files at that webpage.
What it sounds like is you've got Stuffit Expander or some similar
utility configured to auto-expand compressed files, and it's messing
the file up somehow. If it's a hangover from a former Leopard
installation, maybe the problem is the utility isn't quite compatible
with Snow Leopard.
Another possibility is your browser is doing this. Check its
preferences for something like "auto-open downloaded files".
