I have downloaded a zip file from a book site. When trying to unzip the file, windows told me that it was blocked. I followed the Windows Help advice by opening the zip file 'Properties' and clicking 'Unblock'. This has made absolutely no difference, I still cannot open the file.HELP!!!!4 people need an answerI do too

Same, it just blocks them but I don't even get the box to unblock them.Sory to everyone if it is a really stupid question or if it has nothing to do with the origonal quesiton.
