Cannot open a word doc attachement from Outlook 2002

When we attempt to open a word attached document from an email an
'Attachement Security Warning' appears and our only option is to save the
document, 'open' is missing.

I have read through and attempted the most popular solutions on the Internet:
adding Level1Remove to the registry, and 'RemoveWarningFIleTypes'
___________________
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Outlook\Security]
"AddWarningFileTypes"="qqq"
"RemoveWarningFileTypes"="DOC;XLS"
"Level1Remove"=".doc;.xls;.ppt;.rtf;.txt;zip;mdb;.htm;.html;.pdf"

However, I am puzzled, it appears (from Internet documents that I have read)
that word docs should not be prevented from opening from an email to begin
with. What is preventing me from opening a word docuement as an email
attachement and how do I stop this behavior?

Thanks.
