pause
exit

now save that as messenger.bat
this should change to a bat file if not go to.my documents>tools>folder options>untick !"hide extension for known file types" then resave it...
once done double click the messenger.bat

when you have finished it will say press any key to continue.press any key and it will shut the bat down...
now try and log back into messenger

let me know if that does not work
also check your firewall is not blocking messenger,, if it is unblock it.
