i turned on my laptop but the usual window of W.L.Messenger to start the session didn't appear at start. i double-clicked the icon of Messenger on the desktop, still the window didn't open, it only appeared the small icon on the toolbar next to the clock but it desappeared when i scrolled over it without giving me a chance to click it. i have not been shown any error message. i have tried reparing Messenger and restart the laptop, uninstall and reinstall messenger but without any result. the old MSN Messenger works properly but Windows Live Messenger still doesn't work. i have sent an e-mail to messenger support but i haven't got a response them yet.
