Not able to see pdf file in my preview

Have added pdf files before but for some reason now when I try to view the item I get the following message:

“Your current security settings do not allow this file to be downloaded”

Why am I getting this on my preview?

Let me try once more… I want to add a newsletter to my website. It was sent as a pdf file. When I click on it to preview it says
“Your current security settings do not allow this file to be downloaded” Can someone explain what this means and how to get around it.
I was able to use a pdf file before, but that was with my old PC Windows vista with IE6 and 7. I now have Windows 7 and IE9, both of which I hate.

This relates to your browser settings, and is not really a web design question.

Try the Microsoft page for IE9 Security Settings or this one for [URL=“http://www.microsoft.com/en-gb/security/pc-security/ie9.aspx”]Security in IE9.
