Cannot See Messages

[Monty]

I am using Microsoft Outlook 2K.
I can send and receive email no problem. I can see who has
sent me email, the subject and when it was received.
However when I open the message I cannot see the content,
it is blank. Even the Preview Pane is blank. If I click
reply or reply all I can then see the original message
which is copied below my signature. Currently if I want to
read any received email I need to click reply/reply all
then close this reply window if I do not want to reply.

Has anybody experinced this problem. I have reinstalled
office and applied all the updates.

Thanks in advance.
Monty
