Error when viewing attachments (published to web)

Hello,

I'm receiving the following message when I try to view attachments in my e-learning modules that I've just published to Web format.  I'm viewing the presentation using the View Presentation button after publishing. 

"For viewing attachments when presentation is not playing from a website, view the Knowledge Base article located at http://kb.articulate.com/kb/000669.php".

This article speaks of Internet Explorer 6 (I have 8).  Also I'm pretty sure I've viewed attachments like this before without any difficulties.
