Received a notification that a new version of GWM was available; DL'd it; ran it; everything was working fine. Shut down the machine.

Restart the machine this morning, attempt to start GWM and get this:
"GroupWise Messenger cannot start because its configuration has been damaged. Please re-install."
Don't want to reinstall GWM whose ". . . configuration has been damaged."

Please adivise.
