.sit file from Nikon opens into a bunch of gobbledegook?

[Psurfer]

I downloaded the Nikon Scan sw for mac, NS4.sit (29.5MB), I had the Open with Stuffit expander button clicked, and...
It opens up a bunch of nonsense symbols w/the Stuffit copyright info at the top. Command-i says it's a plain text file....
What am I missing?

There was a smaller file version (3.3MB) of this I since also dl'd from the Apple site, w/about the same result.

Opened fine for me with this:

Thanks, that did the trick.
