[Ham-Computers] E-Mail problem.

[KD7JYK DM09]

I've never seen this.

Windows XP, home edition, build 2600.

Microsoft Outlook Express 6.

I have about one hundred folders for sorting incoming e-mail.

One is entitled "Antennas" and has 66 messages in it, things I've saved for 
reference.

Suddenly, after running fine since early 2010, this is the ONLY folder that 
gives the following message when attempting to view ANY message within that 
folder:

Message has not been downloaded
Outlook Express has not yet downloaded this message.
To download the message:
Click here.
Press Space.
Outlook Express

Any ideas of the cause and cure?
