Vista - Bad Image Error message...Help

New computer running Vista Home Premium and Windows Mail. Get an error that
says "Bad Image" and the exeption below using Windows Mail when I open posts
in a stationery Newsgroup containing scripts. I have no trouble viewing
these on other computers running XP and Outlook Express.

What I've done to try to remedy:
Installed additional .dll's as suggested by stationery NG experts-still get
error
Changed IE7 security settings to ALLOW everything - still get error
Shut down anti-virus apps temporarily - still get error (using AVG Free)
Installed different anti-virus program (Norton 360) - still get error
Shut off email monitoring in anti-virus programs - still get error

Strange thing, sometimes when I shut down Windows Mail and open it again,
the error doesn't happen until I shut it down and open it again and then it
is back - mystifying!

Here is the message in the Bad Immage error box:

Exception Processing Message 0xc000007b Parameters 0x75CB023C
0x75CB023C 0x75CB023C 0x75CB023C

Hope someone can help. Thanks.
