As an alternative Download and open with "Stuff it expander" http://www.stuffit.com/
Right click on your zip file and "open with."
The default ArchiveUtility for opening ZIP files seems to be a little buggy in OS X 10.8.2.

I'm confused, because I thought that OS 10.6.8 opened Zips automatically when you double clicked on them. Then, I was told to right-click and "open with" an application - thus, trying to open the zipped PDF files with a PDF reader...I guess I will have to download an un-zipper?

If the unarchiver built-in to OS X doesn't work with .zip files (and I've no idea why it isn't working) you could always download "The Unarchiver" from the App Store - it's free, I believe, and handles almost every flavor of compressed files.
