Amtrak F7's

I downloaded an Amtrak F7 set from here:
http://railworks.banal.net/downloads/downloads.html
And all the files seem to be there. But when I load it up in the editor, nothing shows up on the rails. I see the names there, I click on them, but nothing appears. I don't see anyone else using this pack (as searched on Google), so does that mean that it's just a broken set?
Is there a way to fix it?
