Look at one more thing... If I was at your computer I could figure this out in just a second or two, but I am not.
Anyways, re-download to where you usually save your stuff. Right-click on the file and make sure that it has ".zip" as the file extension. Then you are ok. This is what I think is happening, Zip files somehow got associated with Microsoft Word, I imagine the file that you downloaded has a WinWord icon but is really a zip file. GOD BLESS WINDOWS!!! Don't ask me how to re-associate files, somehow .PDF files on my comp got associated with some accesscibility program! And I can't figure out how to change it.
