Need MS Outlook HELP FAST!

Hey, I'm trying to get an e-mail sent out for my boss, with a .zip file attached to it. I filled out the e-mail and went to INSERT, FILE.
However, when I select the file I can click "Open" or "Cancel". I click "Open" and then the button caption changes to INSERT, I click the dropdown on the button and choose file. NOTHING HAPPENS. It won't attach the zip file! Why NOT! I checked in outlook help, and .zip is not a blocked file type. Any suggestions? I need to get this sent out soon. Thanks

I don't use Outlook, but I just opened it and opened a new message and went to Insert->File and attached kleztool.zip, it put it in the little window near the bottom of the message. It has the zip file icon and the filename underneath. It doesn't do that for you?
