Blank bodies for an entire folder in WorldClient

All the messages in WorldClient in a certain folder have blank bodies.

First, look at the folder on the MDaemon server using Windows Explorer. If you open the messages here with a text editor such as notepad, do they open and do they have data?

If they do have data, please check for a LCK file for their account under \MDaemon\LockFiles. Delete this file and log off and back in to WorldClient.
