Hello.
To use the script, make sure to make Windows Live Messenger remember your passwords ("Remember my password" for each account you wish to use) and to enable "Sign in automatically".
If you haven't already set the list of emails to use, go to
theLaunch > Accounts Configuration. That is basically a list of emails that will be opened automatically. It is essential, so that the script knows what to open.
Feel free to contact me to mplus.leo@gmail.com as I don't come to the forums that often.
