lost kmail message bodiy after upgrade

I just upgraded my kde to the latest via apt-get (kde3.1.1), Now I cannot see the body of my messages. I have tried changing fonts and font/background colors but still cant see the message. The Subject list and the Folder lists are just fine. If I double click on a message header a window pops up but it too is blank. Can anyone tell me what to change to get my messages back via KMail?? Mozilla works fine but I prefer kmail. TIA Richard
