Disable Window's Messenger

[Gene Oliver]

I receive an error message "you have been signed in to
Messenger on another computer." I have no other computer,
but I do use MSN (not Window's) Messenger. Both seem to
be opened on automatically signing in. How do I
automaticall sign in to only MSN Messenger, and disable
Window's Messenger? Please advise. eeo
